Recently we've noticed significant time increase in our pipelines.
It happens randomly, but the "Build setup" step can take even 20 mins, It seems to be stuck on `Downloading cache` step.
We run our pipelines on self-hosted docker runners. I recently updated them to v3.6.0. but it didn't help.
We've verified that the machine they run on have stable internet connection.
What might be the reason for Build step to run so long?
