I don't want to be an alarmist, but I'm getting the feeling that Twitter has been brought down. I'm getting a time out error every time I try to access via TweetDeck or even the Twitter home page.
All other websites are working just fine.
Please try Twitter and let me know if it's working for you, or if there's some known issue floating around out there? If it turns out to be just me, I'll gladly delete this diary.
