RaaS Calls Fail With Tenant Unavailable During Weekly Server Patching
The error tenant is temporarily unavailable due to server patching
What it means
Workday takes each tenant briefly offline for its regular weekly server patching window, and a RaaS (Report-as-a-Service) call made during that window returns a message saying the tenant is temporarily unavailable due to server patching instead of report data. It looks like an authentication or connectivity bug but is actually just bad timing against Workday's own maintenance schedule.
Troubleshooting
- Check the exact time the call failed against Workday's published tenant patching window for your pod and tenant, this is usually a fixed weekly slot.
- Confirm the error isn't actually a credentials issue by retrying the identical call a few minutes after the patching window ends.
- If failures cluster consistently around the same day and time every week, that's a strong signal it's the patching window and not an intermittent integration bug.
- Rule out ISU password expiry separately, since a coincidentally-timed password change can produce a similar-looking failure; test with a fresh, confirmed-valid credential if in doubt.
⚡ Quick fix
Retry the RaaS call outside the tenant's scheduled patching window.
✓ Permanent fix
Build a retry-with-backoff around scheduled integrations that call RaaS, and avoid scheduling recurring RaaS-based jobs during your tenant's known weekly patching window in the first place.
