As a paying customer of Hosted Sentry or Sentry On-Premise you have access to various forms of support; and if you are using the Open Source version you can get in contact with the Sentry community for questions.
The availability of the Sentry cloud hosted installation is independently monitored from outside the infrastructure. To monitor the availability, get notifications and read status updates about outdates you can visit the status page at status.getsentry.com. There you can also subscribe to email and SMS notifications.
We also update the twitter feed @getsentry with status updates.
We offer community support through at forum.sentry.io. This is a great place to provide product feedback, get help and advice with various issues, as well as to take part in the larger Sentry community.
If you’re looking for support on a specific SDK, check the documentation specific to that SDK. Several SDKs are maintained by the Sentry team, whereas others are not. Nearly every SDK also has its own bug tracker, which is generally where the code lives (i.e. on GitHub).
