If you still have your project on GitHub and think that it is a public project, try this: Log off (eg. using a private tab), go to your project, and try reading 3-4 issues. Chances are you're Too Many Requests'd for a few minutes before you even got a decent overview of the project's state. Is this then still a public project?
(For comparison, #Codeberg might run you through a round of Anubis, which is not great either, but still way better, and they run on a tiny fraction of MS's budget.)

@chrysn Since a month or so we're no longer using Anubis for crawler protection. The new protection is from our experience less noticeable than Anubis. ~g

@Codeberg Thanks, always happy to be corrected, an even more so in this case.

@aliceice we have deployed https://iocaine.madhouse-project.org/, it works great so far, but we still have anubis around in case we need to urgently switch back due to changed patterns or whatever. ~f
