Seeing auth succeed but push fail was an exercise in hair pulling.

Same, even started adding new ssh keys to no avail... (I was getting some nondescript user error first, then unhealthy upstream)

Would love to see a global counter for the number of times ‘ssh -T git@github.com’ was invoked.

same, i've started pulling my hair out, was about to nuke my setup and set it up all from scratch

lol same. Hilarious when this shit goes down that we all rely on like running water. I'm assuming GitHub was hacked by the NSA because someone uploaded "the UFO files" or sth.
