How SutramX detects Heroku problems
SutramX customers monitor Heroku and the services that call it. When those checks fail for at least 3 different customer accounts at the same time, with timeouts, 5xx errors, connection or TLS failures, SutramX marks Heroku as degraded and adds “likely external” to the affected customers' incidents and alerts. Only aggregate signals are published here: never a customer, a monitored URL, a response time or an exact number of accounts. How vendor outage detection works.
Frequently asked questions
How do I know if Heroku is down?
This page shows what SutramX's own uptime checks of Heroku see, across customer accounts, updated every minute. For the vendor's own word on an incident, see Heroku's official status page. To tell whether a failure is yours or Heroku's, monitor your own integration: SutramX marks an incident "likely external" when Heroku is failing for several customers at once.
Is this Heroku's official status page?
No. These are signals from SutramX checks, not an official Heroku status page. SutramX often sees a problem before a status page is updated, but not always.
Why does it say "Not enough data"?
SutramX only says Heroku has no problems when enough different customer accounts are checking it at that time. With too few checks it says it does not know rather than guess.
What counts as a disruption?
Checks of Heroku failing for at least 3 different SutramX customer accounts at the same time, with timeouts, 5xx errors, connection failures or TLS errors. Errors that point at the caller, such as 401 or 404 responses or rate limits, do not count. "Likely outage" means it was failing for most of the accounts that check it.
