PeasantDave: Is twitter totally down right now?
Captain Tapole: It is for me. And I woke up early for no reason then.

I believe it is, indeed, totally down.
ukiyo e: I’m not getting updates.
Don’t Panic!
dmmagic: Oh thank goodness I still have a source for updates. I tried to go to Twitter to find out if Twitter was down and IT WAS DOWN!!1!
GPIA7R: I want to tweet about twitter being down.

But I can’t.

From instant messenger:

(09:23:06 AM) spiritg21: How can I do work when Twitter is down so I can’t Tweet about doing work?
(09:23:06 AM) scorpius42 <AUTO-REPLY> : I’m not here right now
(09:23:13 AM) spiritg21: is what I want to know
(09:23:21 AM) scorpius42: lol
(09:23:26 AM) scorpius42: I can’t function!
(09:23:41 AM) spiritg21: What’s the point of life if I can’t tell my hundreds of followers about it?!

So, of course, I’m writing a blog post about it. You know, just to make sure everyone else knows Twitter is down.
