I fixed the grub issue on the pixelfed.social server, now I can fix the actual issue and restore service in the next 15 minutes.
Sorry about the outage, no data was lost, a mis-configuration combined with routine maintenance lead to this failure.
I'm getting better at devops tho, so thank god I was able to fix this myself and now I'm looking into better redundancy and procedures to prevent this in the future.
@dansup great !
