Yes, the server was having issues for a few hours today. Once it was reported, @[email protected] 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.
