Yeah, my apologies. It is a TODO item:;a=blob;f=TODO;hb=HEAD

- Git retry step is broken. Looking at the code it only works for
  incremental updates, not for mode='full', method='fresh' which we
  are using. Given we often already use srcdir != builddir we might
  just use incremental mode. Or we could fix the code?

I see there was just the following commit upstream:
git: Do not throw on intial _fetch() failure if retry or clobber

Maybe that would fix it. I'll see if I can backport that to our release
or hope there will be a new upstream release soon to upgrade to.

Frank, could we add the worker IPs to some allow list on sourceware?
There are 25+ workers now though (hurrah for success!)
