Hello,
We have been using Office 365 since long and have setup more than 100 subsites.
Recently we have found some weird issue regarding REST API calls that we are making. It throws 503 error while creating further subsite. We have already increased resource quota from 300 to 4000 to the same site collection.

We tried to contact MS Support, but didn’t get proper answers. Can anyone please suggest how to troubleshoot this further?
Thanks,
Ashish
Previously, we were using static URL of sp.js,sp.runtime.js, core.js etc. other Microsoft libraries in master page. but MS is also upgrading those files so we changed to dynamic way in master page to render all latest JS library and it started working fine. hurray!
so we thought, it may be latest JS library issue.– oh no wait…
But today it happens again and we are again trying to find why such things happens.
Appreciate your feedback/suggestion.
Thanks
Jinesh
To add to your previous comment, you aren’t being throttled are you? (It would say in the error).
503, as Mark said, generally means the service is down.
Hello Beau,
Sorry for delayed response. Same API was working until we reach to 100+ subsites. Now it always fails to create new sub-site based on template.
Thanks,
Ashish
A 503 is a strange one. Means this :
“The service is temporarily unavailable for maintenance or is overloaded. You may repeat the request after a delay, the length of which may be specified in a Retry-After header.”
Can you test the call out in the Graph Explorer does it work there?
