How does Salesforce behave during scheduled outages?

If you have a scheduled outage with Salesforce in which Salesforce is ‘Completely unavailable’ what error message does a client of the APIs see when someone tries to call it?

Is it a login failure? A 500 server error?


For scheduled outages, it is usually a 503/Server Unavailable

However, those can also happen for unscheduled outages (that, or a 500/Internal Server Error)

We’ve run both apps against the SOAP API for years, and some more recent apps against the REST API (Apex REST). I don’t recall ever seeing a different error code.

Additionally, you should code for timeout errors like Atul suggested since when Salesforce is having a bad day (“performance degradation”), the requests will probably never return at all.
