I thought it was just me, didn't think anyone else noticed it. I figured from the error that it was a backend server problem or that a user limit had been reached by accident. I was worried after that, that it was a DDOS or purposeful attack. But the mods said multiple times that they have backups for if it ever happens. If it helps anyone to know, one of the mods had this to say in one of the | threads | that I read.
"We have contingency plans in the case that something is suspended or taken away from us, such as daily backups, alternative/mirror domains, and alternate providers. If Cloudflare dropped us, we could be back up in a matter of minutes. If our hosting provider dropped us, we could be back up in a matter of hours, and if our domain is suspended, we could switch to an alternative domain in a matter of minutes. We have been planning for the worst for years, and we are confident even if they coordinated all those takedowns at the same time (which is very unlikely), we could be back online within 24 hours. Knowing what I know today compared to 2 years ago, we are in a much better position today than ever before."
