Notification delivery

What to do

• Check whether you use Sentry in eu, us. Check your stack

  Paste a package.json, lockfile, Terraform or a list of domains at down.guide/stack to see every provider you depend on.

• Confirm your retries, queues and scheduled jobs caught up after the 4h 58m it lasted.

  Anything that failed between 2026-06-11 09:50 UTC and 2026-06-11 14:48 UTC may need a replay.

• Subscribe to Sentry's feed to hear about the next one first. RSS feed

  https://down.guide/feed?provider=sentry works in Slack (/feed subscribe), Discord feed bots and any RSS reader.

5. monitoringJun 11, 2026, 1:23 PM UTC

   We have identified an issue with one of our cloud providers that might have caused some alert notifications to not fire starting at around 4:00 AM GMT+2. Since around 1:30 PM GMT+2, alert notifications are now fully operational in the US region, while delivery is still partially degraded in the EU region.
