Random 503 Errors for Webservice API

Hi all. Have an API webservice deployed on Render, and essentially one out of 10 or so API calls always results in a cloudflare 503 error (i.e. the API service does not even receive the request).

I don’t see any service status issues, but this has been consistently happening since initial deploy. I am in the Singapore region.

Any advice?

Hi @50m,

We’re happy to look into this. Can you let us know the name of the service, and any steps we can take a reproduce the issue? Please feel free to email support@render.com with these details if you’d prefer to not post them here.

I BELIEVE I’ve found the cause, a periodic non-async task that might have been blocking. So far so good, will post back here if it returns after this change is in place
