Re^2: Perlmonks.com and Perlmonks.net now redirect to Perlmonks.org

These errors come when the backend is overloaded.

This problem still happens, since now the TCP ports are not exhausted anymore, but the bots are still hitting the site a lot and the caching on Fastlys side is not yet there/set up well enough to give these bots a good answer. We reject them more quickly and now hit 40 requests/s easily, but that does not mean that logged-in users always get a connection to the backend unfortunately.

It might also be the case that all the bad bots are "doing a Yahoo" and caching the old DNS for much longer than the TTL and therefore still hitting the origin servers directly. Might be worth asking Pair to restrict access to those (at the firewall level) only from Fastly sources. 🦛	[reply]
