Hi, we have a python app using App Engine Flexible, and for some reason, it just started throwing 503 errors and failing.
There was no spike in traffic and this version had been deployed for the last 6 days with no issues. Basically, nothing changed.
We tried to let the version self-heal, but it wasn't working. The version entered a loop where it would start and then shutdown continuously.
Finally, I gave up and deployed a fresh version, which works as expected.
Can someone help explain why this might have happened and how to prevent it in the future?
Thanks!

As of now there isn't knows issue reported on the App Engine.Looks like it could just be a transient issue. Let us know, if it still persists.

I am also getting intermittent 503 status over the last few weeks, in one of my Flex Env Services, but not others. The response is as below. The Cloud Console Log Viewer does not show this HTTP request at all.
In my case, my script is automatically starting Flex Env Version. It then sends a curl request to check that the Version is live. This succeeds. About 30 seconds later, it sends another curl request, which experiences this failure.
The Service is written in Java.

It just happened again but on a different App Engine Flexible service. This one had been running perfectly fine, and like the previous case this service just inexplicably stopped working after 6 days. Not a good experience.
