Multi-Region Monitoring

Your site works here. Does it work everywhere?

A CDN edge serves stale JavaScript in Frankfurt. A geo-redirect loop breaks checkout for APAC visitors. DNS geo-routing sends São Paulo traffic to a decommissioned origin. Your single-location monitor in Virginia says everything is fine. Sitewatch runs checks from multiple regions so you catch regional CDN failures, edge-specific breakage, and location-dependent issues before your users report them.

  • Detect CDN divergence where one edge serves broken assets while others work fine
  • Catch region-specific failures invisible to single-location monitoring
  • Identify geo-routing misconfigurations and location-dependent redirect loops

Beyond single-location checks

One location check gives you a false sense of security

CDN edge divergence detection

Your CDN has dozens of edge nodes. When one serves a stale deploy or broken asset, single-location monitoring sees the healthy edge and reports all clear. Multi-region checks expose the divergence.

Region-specific failure visibility

Geo-targeted redirects, region-locked content rules, and location-based routing can break for specific markets while working perfectly in others. You need checks where your users actually are.

Geo-routing misconfiguration alerts

DNS geo-routing can silently send traffic from entire regions to decommissioned origins, wrong data centers, or misconfigured backends. Multi-region monitoring catches routing failures that single-location checks cannot see.

Different users, different realities

Your European visitors get a different response than your US visitors. Different CDN edges, different cached versions, different TLS termination. One check location cannot tell you what all your users experience.

Stale cache detection across edges

After a deploy, some CDN edges purge correctly while others serve yesterday's broken bundle. The result: intermittent failures that depend on which edge a visitor hits. Multi-region checks catch the inconsistency.

Post-deploy regional verification

Your deploy succeeded in your CI pipeline. But did the CDN purge propagate to every edge? Multi-region checks verify that all locations serve the new version, not a mix of old and new assets.

Regional failure detection

Regional failures your single-location monitor misses

CDN and cache divergence

  • Stale assets served from specific CDN edges after a deploy
  • Cache purge failures leaving old JavaScript or CSS on regional nodes
  • CDN edge serving MIME-mismatched assets in some regions but not others
  • Different asset versions across edges causing intermittent breakage

DNS and routing issues

  • DNS geo-routing sending regional traffic to wrong or decommissioned origins
  • Geo-targeted redirect rules creating loops for specific locations
  • Regional failover misconfigurations routing users to unhealthy backends
  • Anycast routing inconsistencies across geographic regions

Content delivery failures

  • Region-locked or geo-fenced content returning 403 for certain locations
  • Locale-specific pages returning wrong language or broken templates
  • Regional compliance redirects breaking page functionality
  • Edge-computed content returning errors for specific geographies

Multi-region checks

How multi-region monitoring works

01

Check from multiple regions

Sitewatch fetches your pages from geographically distributed check locations. Each region runs the same full-page verification independently -- parsing HTML, extracting assets, and verifying delivery.

02

Compare results across regions

Results from each region are compared. When one region returns failures that others do not, Sitewatch flags it as a regional divergence rather than a global outage -- giving you precise, actionable information.

03

Confirm with per-region retries

Each regional failure is confirmed with 2-of-3 retry logic within that region. This eliminates transient network blips while catching persistent, location-specific failures.

04

Alert with regional context

Alerts include which regions are affected and which are healthy. You know immediately whether it is a global incident or an edge-specific failure, so you can target your response to the right CDN node or DNS config.

Stop assuming one check location tells the whole story

Your visitors are global. Your monitoring should be too. Free plan, no credit card required.

Why multi-region

Single-location vs. multi-region monitoring

CDN edge failures

Single-location monitoring:Invisible if your check hits a healthy edge
Sitewatch multi-region:Detected by comparing results across regions

Geo-routing issues

Single-location monitoring:Cannot detect regional DNS misrouting
Sitewatch multi-region:Catches traffic routed to wrong origins per region

Cache purge failures

Single-location monitoring:Reports success from one edge
Sitewatch multi-region:Verifies purge propagated to all regions

Regional redirect loops

Single-location monitoring:Not triggered from monitor location
Sitewatch multi-region:Detected in affected regions

Failure context

Single-location monitoring:"Site is down" — no regional detail
Sitewatch multi-region:"EU-West failing, US-East and APAC healthy"

Post-deploy confidence

Single-location monitoring:One location says deploy is live
Sitewatch multi-region:All regions confirmed serving new version
