Outage today (2023-07-31) from 02:00 UTC - 05:45 UTC
Lemmy.world has been down between 02:00 UTC and 05:45 UTC. This was caused by the database spiking to 100% cpu (all 32 cores/64 threads!) due to inefficient queries been fired to the db very often.
I’ve collected the logs and we’ll be checking how to prevent this. (And what caused this)
