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)

    Every Lemmy update:

    “We fixed some performance issues by optimising some queries.”

    Also: “To balance it out, we added some new even more inefficient queries.”
