So it turned out another server on the same rack as our one was experiencing a DDoS attack, which affected us as well. Lemmy seems to have been pretty stable for me the last couple of days, so I've started reenabling things. Apologies about the downtime we have had recently, hopefully this is better from here on out.
Also if you missed it, go and complete the Lemmy.nz Census.
Also, 5 sleeps until our 1 year birthday!
