Getting mentioned by @Gargron is the ActivityPub version of the slashdot effect
@Gargron Yeah, but I'm the weirdo who runs Apache and not nginx
It just turns out that Apache's max workers was set really low and I kept hitting it, despite being nowhere near out of resources on my box
But thanks anyway <3 I'll keep that in mind if I do switch at some point
@KS Surely there's an equivalent for Apache - if not, you can also just use Varnish between Apache and Puma.
@KS Sorry. Please use the nginx proxy cache it helps with this https://github.com/tootsuite/documentation/blob/master/Running-Mastodon/Tuning.md#using-nginx-proxy-caching
