Hi, when you go to https://bugs.gentoo.org/ you will see a link to https://bugs.gentoo.org/bots.html which contains a list of cached bug lists like https://bugs.gentoo.org/data/cached/buglist-UNCONFIRMED.html which will currently (not automatically) redirect to https://infra-status.gentoo.org/?status=UNCONFIRMED which seems to be invalid (at least the requested content isn't served from the target URL).
Please try to clear your cache. We used a 302 to the infra-status page for the maintenance but that has been removed already so those links should work again.
Yep, fixed. Thanks!
