@arebelspy, or another mod - can anyone tell us what happened last week?
Yes. Thanks for the @ when you need my attention. :)
It was not a DDOS, just a mistake.
Per the forum admin, the issue was "10% software 90% [admin] error." Server was inaccessible (due to software error), was manually shut down, then life issues came up for the admin, who neglected to turn it back on. MMM noticed after about a day, PM'd admin, who went "whoops!" and server was successfully rebooted.
I was out of the country in Germany from Wed - Monday, not on the forums at all, so I only heard about it via CC'd emails from them. Had I been home, likely I'd have noticed earlier and ping'd him.
Human, made mistake, we all hopefully went outside a bit more that day. Shouldn't be an ongoing issue.
Cheers!
