Background

What is Catchpoint?

Catchpoint is an enterprise internet performance observability platform founded in 2008 by Mehdi Daoudi and Michael Behrens, both alumni of DoubleClick (Google's advertising technology business). That origin matters: DoubleClick ran global ad-serving infrastructure where milliseconds of latency directly affected revenue, and the founders brought that infrastructure obsession to Catchpoint from day one.

Catchpoint's founding insight was that server-side monitoring tells you almost nothing about what end users are actually experiencing. Your application server can be healthy, your code can be fast, and your users can still be having a terrible experience — because between your server and your users lies the internet itself: DNS resolvers, ISP networks, CDN edge nodes, and internet exchange points, all introducing latency and points of failure that server-side metrics are completely blind to.

This is the concept of last-mile performance: the measurement of how the internet itself — not your application — affects end-user experience. A data centre in Frankfurt can have sub-10ms response times, but a user on a regional ISP in Southeast Asia might experience 400ms+ latency to reach it, entirely due to network routing decisions outside your control.

In 2020, Catchpoint acquired WebPageTest — the open-source page performance testing tool trusted by browser engineers at Google, Mozilla, and across the web performance community. This acquisition expanded Catchpoint from pure network observability into page-level performance testing, letting it combine waterfall analysis, filmstrip captures, and Core Web Vitals measurement with its existing network infrastructure.

Catchpoint's target market is large enterprise IT and SRE (Site Reliability Engineering) teams: financial services firms where trading platforms must be reachable from every global region, media companies running high-traffic streaming events, and ecommerce enterprises where a 10-minute outage in a single region translates to millions in lost sales. These are organisations where internet performance is mission-critical infrastructure — not a product metric.

Catchpoint is not self-serve. It requires procurement engagement, onboarding, and typically five-figure annual contracts. This is not a weakness — it reflects the complexity of the platform and the sophistication of the teams it is built for. Understanding this positioning is essential to evaluating whether Catchpoint is the right tool for your situation.

The fundamentals

How global synthetic monitoring works — and why the network layer matters

Synthetic monitoring means running scripted tests against your infrastructure on a schedule, from external nodes you don't control — simulating what real users experience without waiting for real user traffic to reveal problems. Global synthetic monitoring extends this to hundreds or thousands of nodes distributed worldwide, so you can see performance from every geographic region and network type simultaneously.

Points of Presence (PoPs)

Catchpoint operates 800+ monitoring nodes — called Points of Presence — distributed across ISP networks, internet backbone exchanges, data centres, cloud regions, and last-mile residential connections. Each node can run tests simultaneously, giving you a parallel view of how your infrastructure performs from every corner of the internet. The diversity of node types is what makes this valuable: a test from an AWS data centre in us-east-1 and a test from a residential Comcast node in Ohio will often show dramatically different results for the same URL.

DNS monitoring

Before a user's browser can make a single HTTP request, it must resolve your domain name to an IP address via the Domain Name System. This resolution traverses a chain of authoritative DNS servers and takes between 5ms and 200ms+ depending on TTL caching, resolver proximity, and DNS provider health. Catchpoint monitors DNS resolution time and correctness as a separate metric from HTTP performance — because a DNS failure or slowdown makes your site unreachable even when your origin server is perfectly healthy. DNS outages are invisible to server-side monitoring.

CDN and edge monitoring

Content Delivery Networks cache your assets at edge locations worldwide. Catchpoint tests whether your CDN is correctly serving cached content from edge nodes, whether caches are warm (cache-hit ratio), whether CDN routing is directing users to the nearest edge, and whether specific edge nodes are degraded. A CDN misconfiguration — like all requests bypassing the cache and hitting origin — can cause massive latency regressions that look like an application problem but are actually a CDN configuration issue.

Anycast routing

Some services use Anycast: the same IP address routes to different physical servers based on the user's geographic proximity, using BGP to ensure each user reaches the nearest instance. DNS resolvers (like 1.1.1.1 and 8.8.8.8) and CDN edge nodes commonly use Anycast. Catchpoint can test which Anycast node a request reaches from different PoPs — detecting cases where routing is suboptimal or where a specific Anycast node is serving degraded responses.

BGP routing

Border Gateway Protocol is the routing protocol governing how traffic flows between Autonomous Systems — the large networks operated by ISPs, cloud providers, and enterprises. BGP determines the packet path from a user's ISP to your server. BGP route leaks or hijacks can redirect traffic through unexpected paths, dramatically increasing latency or making sites unreachable from specific regions. The 2021 Facebook six-hour outage was caused by a BGP misconfiguration that withdrew Facebook's routes from the global internet, making all its services globally unreachable despite perfectly healthy hardware.

ISP last-mile monitoring

ISPs introduce their own latency, routing decisions, and congestion patterns. A CDN edge node in London might be 3ms from your servers but 80ms from a user on a specific mobile carrier's network, depending on that carrier's peering arrangements. Catchpoint embeds monitoring nodes inside residential ISP networks — so you can see how a user on Comcast differs from a user on AT&T, or how a mobile user on a congested 4G network experiences your site. This is the last-mile gap that data centre testing completely misses.

The critical concept underlying all of this is the distinction between server latency and network latency. Server latency is Time to First Byte (TTFB) — how long your server takes to process a request and begin sending a response. Network latency is the time packets spend in transit across the internet before reaching your server. A fast server with poor network routing still produces a slow user experience. Catchpoint measures both — and separates them.

Platform capabilities

Key features of Catchpoint

Catchpoint has spent sixteen years building infrastructure-scale observability tooling. These are its core capabilities.

Synthetic monitoring from 800+ PoPs

Catchpoint's global node network spans ISP networks, internet backbone exchange points, data centres, cloud provider regions (AWS, Azure, GCP), and residential last-mile nodes. This breadth is genuinely differentiated — no other commercial monitoring platform matches this coverage. Tests run simultaneously from all selected nodes, giving you a parallel geographic view of performance and availability. You can isolate performance by network type (backbone vs. residential vs. cloud) to understand exactly where degradation is occurring.

WebPageTest integration

Since acquiring WebPageTest in 2020, Catchpoint can run full WebPageTest analyses from any of its global nodes. This means waterfall charts, filmstrip video captures, visual progress scoring, and Lighthouse-based Core Web Vitals measurements can be combined with network-layer observability. A performance regression can be investigated at both the network level (is this a CDN routing issue?) and the page level (which resource is the bottleneck?) from a single platform.

API monitoring

Catchpoint monitors REST and GraphQL API endpoints with response time measurement, HTTP status code validation, and response body assertions. This is important for SRE teams monitoring the health of microservices and third-party API dependencies — a degraded third-party API can cause your application to slow down even when your own code is healthy.

Streaming media monitoring

Media companies use Catchpoint to monitor video streaming quality: buffering ratio, bitrate, startup time, and rebuffering events. These metrics are specific to streaming protocols (HLS, DASH) and require instrumentation beyond standard HTTP monitoring. For a broadcaster or streaming platform, these metrics directly map to subscriber churn.

BGP and DNS monitoring

Catchpoint provides dedicated monitoring for network-layer health: BGP route availability and AS path analysis, DNS resolution time from distributed resolvers, DNSSEC validation, and DNS propagation tracking during zone changes. These capabilities are unique to Catchpoint in the commercial monitoring market — they require infrastructure embeds in carrier networks that most monitoring tools don't have.

Real-time alerting with multi-step conditions

Catchpoint's alerting supports complex threshold logic: alert only if 3+ PoPs in the same region all exceed a latency threshold simultaneously, avoiding false positives from single-node anomalies. Alerts can be routed to PagerDuty, Slack, ServiceNow, or Jira. For enterprise SRE teams managing on-call rotations, reducing alert noise is as important as detecting real incidents.

Digital experience scoring

Catchpoint aggregates raw technical metrics (DNS time, connect time, TTFB, render time) into experience scores that business stakeholders can interpret without network engineering knowledge. This bridges the gap between infrastructure teams generating data and business leaders who need to understand what that data means for customers.

Enterprise features

Single Sign-On (SSO), role-based access control, custom SLA reporting, compliance posture documentation (SOC 2, GDPR), dedicated customer success management, and contractual uptime guarantees for the monitoring platform itself. For enterprises integrating performance observability into existing ITSM and compliance workflows, these aren't optional extras — they're procurement requirements.

Honest assessment

Catchpoint's strengths and limitations

Genuine strengths

Unmatched global node coverage — 800+ PoPs across ISP, backbone, cloud, and residential networks is a genuinely differentiated capability no competitor matches at scale.
Network-layer visibility (DNS, BGP, CDN, Anycast) that is completely unavailable in page-speed tools or RUM platforms.
Last-mile ISP testing reveals real-world user experience from residential and mobile networks — the performance gap that data centre testing misses.
WebPageTest integration brings full page-level performance depth alongside network monitoring, in a single platform.
Enterprise-grade reliability, compliance certifications, and contractual SLAs appropriate for regulated industries.
Ideal for organisations where a 10-minute network outage in a single region means millions in losses and requires immediate SRE escalation.

Limitations

Enterprise pricing with no self-serve option — requires sales engagement and typically five-figure annual contracts, making it inaccessible for most teams.
Designed for infrastructure and SRE teams, not product, marketing, or engineering teams focused on application performance.
No AI Fix Blueprints or code-level remediation guidance — Catchpoint identifies network issues but doesn't help your team fix application-layer problems.
No revenue impact modelling — you can't connect a latency regression to an estimated conversion or revenue impact.
No white-label reporting for agencies managing client sites across portfolios.
Overkill for the vast majority of web teams: if you don't have engineers who can act on BGP routing alerts or CDN Anycast analysis, the network observability data provides no value.

Key insight

The infrastructure layer vs the application layer

To understand where Catchpoint and AuditJet each belong, it helps to think clearly about the full stack that sits between a user clicking a link and a page appearing on their screen.

The journey looks like this: a user's request leaves their browser, travels through their ISP's local network, gets routed across the public internet via BGP, hits a CDN edge node (or misses one and goes all the way to origin), goes through a DNS resolution step early in the process, arrives at your origin server, gets processed by your application code, and finally returns HTML that the browser renders into pixels — a process involving layout, paint, JavaScript execution, and font loading.

Catchpoint monitors the infrastructure layer: ISP routing, BGP path health, CDN edge behaviour, DNS resolution, and network latency. These are layers you observe but largely cannot fix directly — you can escalate a BGP issue to your CDN provider or change DNS TTLs, but you don't control the internet.

AuditJet monitors the application layer: Core Web Vitals (Largest Contentful Paint, Interaction to Next Paint, Cumulative Layout Shift), page rendering performance, SEO health signals, and JavaScript execution cost. These are layers you directly control — you can optimise images, reduce bundle sizes, fix layout instability, and implement lazy loading.

Both layers matter, but they are different problems requiring different expertise, different teams, and different tools. Most web teams — product engineering, frontend development, marketing technology — work in the application layer. The infrastructure layer belongs to SRE, NetOps, and platform engineering teams at organisations large enough to have those functions.

The diagnostic question

Ask yourself: "Do I have engineers on my team who could act on a BGP routing alert from a specific ISP in Southeast Asia?" If the answer is no, Catchpoint's network-layer data is not actionable for your team, no matter how accurate or comprehensive it is. Infrastructure observability is only valuable when it is paired with the operational capacity to respond to what it reveals.

Direct comparison

AuditJet vs Catchpoint

These two tools serve fundamentally different audiences with fundamentally different problems. An honest comparison requires acknowledging that Catchpoint is genuinely excellent at what it does — and that what it does is not what most web teams need.

It is worth saying clearly: these tools do not compete. A Fortune 500 media company might legitimately use Catchpoint for its SRE team's network observability and AuditJet for its product team's Core Web Vitals and SEO monitoring — the two platforms monitor different layers of the same stack and surface data to different teams.

AuditJet is not attempting to replace Catchpoint for enterprises that genuinely need infrastructure-layer observability. AuditJet serves the 99% of web teams — product engineers, frontend developers, SEO specialists, performance-focused marketers — who need application-layer monitoring with revenue context, not BGP routing analysis.

Frequently asked questions

Global monitoring and network observability: the essentials

What is internet performance observability?

Internet performance observability is the practice of monitoring not just whether your server is responding, but how the entire network path between a user and your server is performing. This includes DNS resolution time, CDN routing behaviour, BGP route health, ISP latency, and last-mile delivery — all the infrastructure layers between your origin server and the end user's device that can degrade performance even when your application is perfectly healthy.

What is DNS monitoring and why does it matter?

Before a browser can connect to your server, it must resolve your domain name to an IP address via the Domain Name System (DNS). This lookup traverses a chain of authoritative DNS servers and can take anywhere from 5ms to over 200ms depending on TTL caching, resolver location, and DNS provider health. A DNS outage — like the 2016 Dyn attack that took down Twitter and Spotify — makes your site completely unreachable, even though your origin server is perfectly healthy. DNS monitoring tests resolution time and correctness from distributed nodes continuously.

What is a CDN and how does Catchpoint monitor it?

A Content Delivery Network (CDN) is a globally distributed network of edge servers that cache copies of your assets (images, scripts, HTML) closer to end users. When a user in Tokyo requests your site hosted in Virginia, a CDN serves cached assets from a Tokyo edge node rather than routing all the way to Virginia — dramatically reducing latency. Catchpoint monitors CDN behaviour by testing whether edge nodes are serving cached content, whether caches are warm (cache-hit ratio), whether CDN routing is correct, and whether specific edge nodes are experiencing degraded performance.

What is BGP routing and how can it affect website performance?

Border Gateway Protocol (BGP) is the routing protocol that governs how traffic flows across the global internet between Autonomous Systems (the large networks run by ISPs, cloud providers, and enterprises). BGP determines which path packets take from a user's ISP to your server. BGP misconfigurations — called route leaks or route hijacks — can cause traffic to take unexpectedly long paths, or make your site completely unreachable from specific regions. The 2021 Facebook outage was caused by a BGP misconfiguration that made Facebook's servers invisible to the internet. Catchpoint monitors BGP route health to detect these conditions.

What is last-mile monitoring?

Last-mile monitoring tests from residential ISP networks — the actual broadband and mobile connections that end users are on — rather than just from fast data centre nodes. The final hop from an ISP's network to a user's device often introduces significant latency and variability. A site that performs well when tested from a data centre in London can perform poorly for a Comcast user in suburban Ohio if that ISP's peering with your CDN is congested. Last-mile monitoring reveals this gap by running tests from nodes embedded in residential ISP networks.

How does Catchpoint differ from traditional uptime monitoring?

Traditional uptime monitoring (like Pingdom or UptimeRobot) checks whether your server returns a 200 HTTP response from a few locations. Catchpoint goes far deeper: it measures DNS resolution time separately from HTTP connection time, tests CDN edge behaviour and cache health, monitors BGP route availability, runs tests from ISP residential nodes for last-mile performance data, and provides full synthetic transaction monitoring for multi-step user flows. It's the difference between knowing your server is responding and understanding the full network path your users traverse to reach it.

Can AuditJet replace Catchpoint?

No — they solve fundamentally different problems for different audiences. Catchpoint monitors the infrastructure layer: network routing, DNS, BGP, CDN edges, ISP latency. AuditJet monitors the application layer: Core Web Vitals (LCP, INP, CLS), page rendering performance, SEO health, and the revenue impact of performance regressions. A large enterprise might legitimately use both: Catchpoint for their SRE team's network observability, and AuditJet for their product team's CWV and SEO monitoring. For the vast majority of web teams who don't have a dedicated NetOps team, AuditJet addresses the performance problems that are actually within their control.

What is the difference between network observability and web performance monitoring?

Network observability monitors infrastructure: how packets travel across the internet, BGP route health, DNS resolution, CDN behaviour, ISP latency. These are problems you typically cannot fix directly — you can only observe them and escalate to CDN providers or ISPs. Web performance monitoring focuses on the application layer: how your code renders, how large your JavaScript bundles are, whether images are properly optimised, what your Core Web Vitals scores are. These are problems your engineering team can directly fix. Network observability belongs to SRE and NetOps teams; web performance monitoring belongs to product and engineering teams.
