I'm having the same problem. I was signed in and everything was hunky-dory but then I signed out just to test your example... bad idea. Now I'm stuck out!
This happened to me the other day, and I was all confused because normally when a site is down I can Twitter about it but with Twitter down there was nowhere to go. It was only down for a moment though, so problem averted. Still, not sure HN is the right forum for up-to-the-minute chit-chat about what sites are broken...
Twitter is available again for me, so yeah, for me it was only down for a few minutes.
As for whether HN is the appropriate forum to "tattle tale" when a well known website is down? Hmmm... Dunno about this one, I just figured it would be newsworthy, sorry if I wasted anybody's time...
