I think it’s been functionally login-only for a while, unfortunately.
Any time I try to use the site while logged out I immediately hit all sorts of rate limits and spam prevention measures. Issues and pull requests stop loading almost immediately. Searches are extremely restricted, like i think literally one search is all you get sometimes unless you login.
It’s hard to tell how much of this is intentional and how much is GitHub infra not being stable. My daily renovate bot that looks for updates for specific packages times out and encounters errors almost every time it runs and it’s barely doing anything. And it has an api key. I know I’m not hitting limits, some queries just don’t work >50% of the time on some repos.
Sometimes I see there are 200 issues, I click the issues tab, and there are zero. Is GitHub down? Am I rate limited? Do I just need to login? Or I know an issue/PR exists, and it just doesn’t appear when I search for the title or keywords verbatim. I just manually bookmark or subscribe to any important issue or PR now because the UI can’t be trusted anymore.
