Why yes, it _is_ April first. And yes, there _is_ something going on, as of Midnight, April 1st, Eastern Time. (I'm going to bed early so couldn't wait for M*U*S*H midnight. Sorry!)
A note to those who immediately connected a few minutes after @shutdown - it ended up taking me about 20 minutes to get everything properly set up and running, firewalled, etc. So if you attempted a connection during that time that seemed like it should've worked but didn't, then try again.
(And a few people were seeing nothing - may have happened to others. Hopefully that's fixed! If there's any more issues, let me know here!)
