Thread: Mailing list archive access glitches
Over the past few days I've frequently had attempts to fetch a https://www.postgresql.org/message-id/... URL fail with reports like Error 503 Backend fetch failed Backend fetch failed Guru Meditation: XID: 89820252 Varnish cache server It eventually works if I reload enough times. Discussion on Discord says that other people have seen this too. The problem seems noticeably worse right now ... regards, tom lane
Hi!
I believe Alvaro got this sorted last night, but forgot to reply to the thread :)
The root of the problem is "the good old cisco firewall" that keeps on acting up. We've finally gotten to the point that it's scheduled for replacement, so hopefully this type of problem will happen less once that's done.

Hi again!
Turns out it was both this and a DoS attack. Hopefully we've mitigated the attack as well now.
