Having been on the receiving end of things like this: please, make the sleep longer. Adding more requests to already malfunctioning system is not a good way to help in fixing it.
Thanks but no thanks - no way am I doing anything to my core app repos when the repo host is fritzing out. This is one of those moments to go for a walk (or bed, depending on your timezone).
Also pretty much every usage of -f would be better off being --force-with-lease so you're less likely to accidentally clobber someone else's work. I have git fpush aliased to "push --force-with-lease" and try to spread the gospel when possible :)
