I'm not sure what to do with this issue: the test already runs only on longtest builders, and requires access to github.
Test flakes due to I/O or upstream connectivity issues seem to be WAI.

I guess I'll leave this bug open to catch the flakes. Unless there is an apparent builder or configuration issue (which I don't see here), this bug is unactionable.
