Yeah, sorry about the 502 gateway error earlier. Backing up the database can take a minute or two. I was trying to make sure an automated daily backup script would be able to back up the database to an offsite server properly. Seems to have worked though. As for the custom 502 error message, I completely agree. Some new error pages would be great. Especially during backups which would be happening once every night at around midnight.
Everything seems to be working smooth for me today.
