In a recent PR (https://github.com/python/cpython/pull/18057), I received the following error message in the Azure Pipelines build results:

##[error]We stopped hearing from agent Azure Pipelines 5. Verify the agent machine is running and has a healthy network connection. Anything that terminates an agent process, starves it for CPU, or blocks its network access can cause this error. For more information, see: https://go.microsoft.com/fwlink/?linkid=846610

Build: https://dev.azure.com/Python/cpython/_build/results?buildId=57319&view=r...

Is there something on our end we can do to bring the agent back online, or should I simply wait a while and then try to restart the PR checks? Normally I'd avoid doing that, but in this case it's entirely unrelated to the PR.

I think we're at the point where it's probably okay to disable Azure Pipelines as a required check and replace it with the GitHub Actions checks.

But ignoring that for now, I think it's probably best to re-run CI (close/reopen). Just in case the change did actually cause a problem that may only show up on that particular configuration. The agent isn't actually within our control, so it'll be recreated automatically.

(FWIW, the two failing buildbots on the PR are unsupported for 3.9, but haven't been disabled yet.)

This seems the best thread to follow up on, just had a spurious failure backporting a patch to 3.8 from master:

Trying the close/re-open to get CI to re-run...

Sounds good, GitHub Actions CI looks like it's been working smoothly. Since you introduced it, I haven't encountered any issues in my own PRs or ones that I've reviewed.

Thanks for the advice! I figured this would be the best option in this situation, but since I wasn't sure about how exactly the agents worked, it seemed like a good idea to ask first.

I think we're at the point where it's probably okay to disable Azure
Pipelines as a required check and replace it with the GitHub
Actions checks.

But ignoring that for now, I think it's probably best to re-run CI
(close/reopen). Just in case the change did actually cause a problem
that may only show up on that particular configuration. The agent
isn't
actually within our control, so it'll be recreated automatically.

(FWIW, the two failing buildbots on the PR are unsupported for
3.9, but
haven't been disabled yet.)
