Is fetching nixos repository throttled by github somehow?

Hi,

I keep a NixOS/nixpkgs repository locally and sync via git fetch periodically.

Recently I noticed that git fetch might start to hang without any progress.

I haven’t observed such behavior on small repositories.

Does anybody noticed the issue and what could it be?

Yes, when I fetch (or maybe also push) GitHub too much, I end up getting throttled like that. I wasn’t doing anything unusual though. Anyway, I switched to a different workflow since then, having a single bare nixpkgs repo getting fetched hourly usually and I reduce additional fetches. (it’s annoying though, as I have to avoid normal git pull)
