Yeah, and there was also the time last week when they had a similar announcement up but then pulled it during the afternoon. I think actual maintenance is less likely to get postponed because it doesn't depend on the bureaucracy in the same way tat announcements do. I'm going to predict that this is the announcement, with the caveat that they might pull the maintenance message from the site during the day and postpone it again.
Good luck to everyone, particularly those who need it to continue with their studies. I'd certainly appreciate not having to teach for a few years, but I do have guaranteed funding, and I can manage just fine without it.
