Multi-Region Monitoring

CheckOps runs every monitor from multiple regions simultaneously. This detects localized outages, CDN issues, and geographic performance degradation that single-region monitoring misses.

AVAILABLE REGIONS

OPS PLAN (8 REGIONS)

Code	Location	Provider
fr-par	Paris, France	OVH
fr-gra	Gravelines, France	OVH
de-fra	Frankfurt, Germany	ClearCloud
de-ber	Berlin, Germany	ClearCloud
nl-ams	Amsterdam, Netherlands	ClearCloud
be-bru	Brussels, Belgium	OVH
fi-hel	Helsinki, Finland	OVH
pl-waw	Warsaw, Poland	OVH

PRO PLAN (15+ REGIONS)

All OPS regions plus:

Code	Location	Provider
uk-lon	London, UK	OVH
es-mad	Madrid, Spain	OVH
it-mil	Milan, Italy	OVH
se-sto	Stockholm, Sweden	OVH
ch-zur	Zurich, Switzerland	ClearCloud
at-vie	Vienna, Austria	OVH
pt-lis	Lisbon, Portugal	OVH

Enterprise plans can request custom regions including non-EU locations.

HOW MULTI-REGION WORKS

Each check cycle dispatches the monitor to all selected regions in parallel. Results are aggregated with the following logic:

1. All regions UP — Monitor status is UP
2. Some regions DOWN — Monitor status is DEGRADED with region details
3. All regions DOWN — Monitor status is DOWN

This prevents false positives from transient network issues in a single region.

REGIONAL LATENCY COMPARISON

The dashboard displays per-region response times in a heatmap view:

Region         Latency    Status
─────────────────────────────────
fr-par         42ms       UP
de-fra         51ms       UP
nl-ams         48ms       UP
uk-lon         67ms       UP
es-mad         89ms       SLOW
it-mil         112ms      SLOW

Regions where response time exceeds the response_time assertion threshold are flagged as SLOW without triggering a DOWN alert.

CONFIGURATION

Select regions when creating or editing a monitor:

{
  "url": "https://api.acme.com/health",
  "regions": ["fr-par", "de-fra", "nl-ams", "uk-lon"],
  "assertions": [
    { "type": "status_code", "operator": "equals", "value": 200 },
    { "type": "response_time", "operator": "less_than", "value": 2000 }
  ]
}

If no regions are specified, all regions available on your plan are used.

USE CASES

• CDN verification — Ensure your CDN serves content consistently across Europe
• DNS propagation — Detect stale DNS records in specific regions
• Localized outages — Identify issues affecting specific geographic areas
• Compliance — Verify data residency by checking responses from specific regions
• Performance baseline — Compare latency across regions to identify optimization targets
