Yes, the server was having issues for a few hours today. Once it was reported, @TheDude@sh.itjust.works sprang into action and got things sorted out. I don't have the details on exactly what happened, unfortunately.
I have an update to share. Apparently the pictrs service has a habit of not cleaning up its temp files, which then eventually consume all the disc space. That's what happened today. The bug is supposedly fixed in the next version of pictrs. When the server is upgraded to Lemmy 0.19 TheDude will update pictrs at the same time.
The best way is to @TheDude on our matrix channel. This action triggers notifications across all my devices, creating a barrage of alerts that almost always grab my attention, a.k.a a ddos to my sensory system.
@kersploosh@sh.itjust.works explained it well. It was related to a small bug on the pictrs service that I've already reported which they quickly fixed in a newer version. I will tackle this upgrade at the same time as I get this instance up to v19
