To clarify the issues: our bugtracker is being pounded by AI scrapping bots that query every single bug repeatedly all the time. This leads to, effectively, a denial-of-service attack, where the database runs out of memory given so many simultaneous queries. We tried blocking these bots but they change their IP address all the time (likely using cell phone IPs).
As an emergency we had to resort to blocking all IPs except those in a whitelist, so that at least our developers could access the bug tracker. We are looking to a new solution and hope to be able to open up the tracker to everyone soon.
(this is yet another way in which so-called AI is killing the Internet...)
