Check regions

Markdown

Choose which part of the world we check your service from.

By default we check your monitors from the United States. On Pro, Business and MSP you can choose the region a monitor is checked from, so you're testing the experience your users actually get.

A diagram of UptimeTwin's two independent clouds, labelled Cloud A and Cloud B, both marked active and both checking and alerting at the same time Our monitoring runs active-active on two independent clouds across four regions. Each monitor is checked from the one region you choose; if one cloud has an outage, the other keeps checking and keeps paging.

Available regions

  • US West (default)
  • US East
  • Europe
  • Asia-Pacific

When it matters

  • Match your audience. If most of your users are in Europe, checking from Europe reflects their real latency and reachability.
  • Regional issues. A network problem between one region and your host can look like an outage from there but be fine elsewhere. Checking from the right region keeps your results meaningful.

Firewalled services

Whichever region you choose, the checks come from a small, fixed set of IP addresses. If your service only allows known IPs, add ours to your allowlist — see Allowing our checkers through your firewall.
