The server stopped working the other night, and I fixed it what turned out to be temporarily. It went down again tonight and looking into it further I found the server had ran out of disk space.
I’ve added another few GB to the size of our disk, so that should do us another couple years. It puts the monthly costs up slightly which is why I didn’t just throw more space at it sooner. It seems to have ballooned a little recently.
Anyway, there shouldn’t be any more instances of downtime. Fingers crossed.
