How SutramX detects Mux problems
SutramX customers monitor Mux 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 Mux 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 Mux is down?
This page shows what SutramX's own uptime checks of Mux see, across customer accounts, updated every minute. For the vendor's own word on an incident, see Mux's official status page. To tell whether a failure is yours or Mux's, monitor your own integration: SutramX marks an incident "likely external" when Mux is failing for several customers at once.
Is this Mux's official status page?
No. These are signals from SutramX checks, not an official Mux 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 Mux 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 Mux 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.
