Verify that your services are reachable from multiple geographic locations simultaneously. Catch CDN failures, regional outages, and anycast routing issues that a single-probe setup would miss entirely.
When multi-region is enabled on a monitor, every scheduled check is dispatched to all selected worker regions at the same time. Each worker independently performs the check and reports its result back. Monitorion then applies a majority-vote algorithm to decide the true status of your service.
More than 50% of participating regions must report the service as DOWN before an incident is created and alerts are sent. A single region reporting a failure while all others succeed is treated as a regional anomaly — you will still see it in the results panel, but your team will not be paged.
Dispatch
All selected workers receive the check job simultaneously
Execute
Each region runs its own independent probe and records the outcome
Vote
Majority determines overall status; incident created only when >50% report down
Multi-region is available for monitor types where results genuinely vary by location — network availability, latency, DNS resolution, and API responses. Types like SSL certificates or domain expiry return the same result globally, so they always run from a single region.
| Plan | Regions | Notes |
|---|---|---|
| Free | Not available | Single-region checks only |
| Pro | 3 regions | Choose any 3 active worker locations |
| Business | Unlimited | All active workers, including Auto mode |
| Agency | Unlimited | All active workers, priority scheduling |
Open the monitor you want to configure
From your dashboard, click on any monitor name to open its detail view, then select Edit.
Toggle on Enable Multi-Region
The toggle is located in the Advanced Settings section of the monitor form. Enabling it reveals the region selector.
Choose regions or select Auto (recommended)
You can pin specific geographic locations or let Monitorion manage region selection for you automatically.
Auto mode (recommended)
Auto mode uses every currently active worker. As new workers come online they are automatically included in future checks for this monitor — no manual reconfiguration needed. This is the best choice for most use cases.
Save the monitor
Multi-region checks take effect on the very next scheduled interval. No downtime or restart required.
The monitor detail page displays a dedicated Multi-Region Results panel below the response-time chart. For each recent check round you will see:
Green indicator
That region successfully reached your service within the expected response-time threshold.
Red indicator
That region could not reach your service. Hover to see the exact error message and response time.
Yellow indicator
The check timed out in that region. Treated as a failure in the majority-vote calculation.
Gray indicator
No result received yet for this round (worker may be starting up or temporarily offline).
Tip: The overall status badge at the top of the monitor detail page always reflects the majority-vote outcome, not any individual region. Scroll down to the results panel to see which specific regions are experiencing issues.
CDN edge nodes can fail independently. Multi-region checks reveal when a specific PoP is serving stale content or returning errors while other regions work fine.
Cloud provider availability zone incidents, undersea cable cuts, or BGP route leaks affect specific geographies. Multi-region monitoring surfaces exactly which areas are impacted.
Services using anycast (e.g., DNS resolvers, DDoS scrubbing) can appear healthy from one vantage point while a broken routing advertisement is dropping traffic for users in another continent.
Enterprise customers often require that your service is available from multiple continents. Multi-region monitoring gives you the evidence to report on this in SLA documents.
Misconfigured firewall rules or geo-restriction policies may unintentionally block legitimate users. Multi-region checks catch these unintended blocks before your users report them.
Network blips at a single probe location can trigger false alarms. Majority voting eliminates noise so your team is only paged when a genuine outage is occurring.
Multi-region monitoring is available on the Pro plan and above. Upgrade to get started.
