Flaky connections

[sloanesturz]

We're experiencing extreme flakiness trying to check out our own repo in our CI and deploy suites. We're running Github actions hosted at Github and a Github repo hosted at Github.

This is the first step in our job:

   steps:
      - uses: actions/checkout@v4

It hangs until the workflow or job times out.

The specific command that it hangs on is the last step of the action --

  /usr/bin/git -c protocol.version=2 fetch --prune --no-recurse-submodules origin +refs/heads/*:refs/remotes/origin/* +refs/tags/*:refs/tags/*

The debug logs don't show anything interesting. That /usr/bin/git command doesn't ever print anything.
