We had an issue with scheduled tweets/posts not going out starting around 10pm PDT last night (Thursday, October 6, 2011) that was resolved this morning, Friday, October 7, 2011 at 9am PDT.

Any tweets in this eleven hour window should appear as failed in your dashboard so you can easily reschedule them.

We're working on improving the reliability of scheduled tweets and posts. Thanks for bearing with us.
