What it is
A region is a location your checks run from. Every probe runs from at least one region. Run it from several and you learn something a single location can’t tell you: whether an outage is global or just regional, and how fast your service responds from each part of the world.
If your site is unreachable from Europe but fine from the US, one region checking from each shows you that split the moment it happens, instead of leaving you guessing why some users report problems and others don’t.
Where checks run from
Checks currently run from:
- Seattle, USA
- Nuremberg, Germany (Europe)
More locations are being added over time. The regions you can pick appear in the probe form, so the list there is always current.
Choosing regions
When you create a probe, pick the regions it should run from. Each region you add runs the full check on your chosen interval and reports its own results.
On the Free plan a probe runs from a single region. Multi-region checks are available on paid plans, where you can run a probe from every available region.
Reading per-region results
A probe’s status is worked out from its recent checks across all the regions it runs in, so if a check starts failing from one location, that shows in the probe’s status right away.
Open the probe to see the breakdown. Each region gets its own row with its status, uptime, and response times, so you can tell a local problem (one region down, the rest up) from a global one (every region down), and compare latency between locations.
Next steps
Add a probe and choose its regions from the probe form. New to probes? Start with the HTTP, TCP, or Domain guide, or see how a probe’s state is worked out in Probe statuses.
