This seems to have started happening around 19th of July. Potential commits in the area that I'm seeing #117540 or #117667. @antonfirsov @rzikm Any ideas about what could have started causing this ?

[rzikm]

@BrzVlad I see the failures also on a PR from 18th, on #117748, maybe that change is relevant? cc @davidnguyen-tech

e.g. https://github.com/dotnet/runtime/runs/46277027211

edit: but that PR was merged on 21st, so it is possible that there is a different root cause altogether

Also, don't use too broad patterns for matching the exception, TimeoutException.*System\.Net would match ALL timeouts in the entire networking area.
