Sentry uptime
Measured from multiple regions every 30 minutes. Percentages count only checks that returned an availability answer — 30 days measured so far. A dash means that window does not yet hold enough measured days to publish a figure.

Reachability by region
Each region runs its own request from a different part of the world. A service can be up for one continent and down for another, which is usually the first sign of a routing or CDN problem.
What Sentry does
Sentry is an application monitoring and error tracking platform that helps developers identify and fix crashes in real time. It captures exceptions, performance data, and session replays from web, mobile, and backend applications. Sentry is used by thousands of engineering teams to maintain application health and reduce time to resolution for bugs.
What an outage looks like
When Sentry is down, error reports from your applications will fail to be ingested. This means new crashes and exceptions go unrecorded, creating blind spots in your monitoring. The Sentry dashboard becomes inaccessible, preventing you from investigating existing issues. Alert notifications for error spikes will not fire.
What to do about it
Check status.sentry.io for the current status. The Sentry SDKs in your application are designed to fail gracefully, so a Sentry outage will not crash your application. Events are buffered locally in the SDK and some may be retried. Check your application logs as a fallback for error visibility during the outage.
Is it down for everyone, or just you?
If this page says Sentry is up but it is not loading for you, the problem is between you and them. Run a check against any URL from all 18 regions to find out where it breaks.

How we measure this
- We request Sentry's public endpoint every 30 minutes from Fly.io regions across six continents — 18 of them answered the most recent check.
- A region counts as down only when it gets no usable HTTP response. A
403or429means the origin answered and refused us, which we report as blocked, never as an outage. - A single failing region is treated as probe noise. We only change the verdict when two consecutive cycles agree.
- Response times average only the regions that actually served the page, so a timeout never inflates the number.
- Where Sentry publishes an official status feed we read it too. An all-clear from the vendor can soften an unconfirmed degradation; a vendor-declared outage only worsens our verdict when our own checks corroborate it.
