Timeline delays this morning 5 years ago
We are currently investigating a problem causing many users’ timelines to be delayed. We will update with status here shortly.
Update (10:50a): Timelines remain stale for users. We are deploying fixes to address the problem.
Update (12:27p): This issue has been resolved and timelines are updating normally once again.
Update (12:54p): The problems this morning were caused by a bug triggered by an edge case in one of the core services that powers Twitter. We have already fixed this bug and are making additional optimizations based on what we learned.
Most users are seeing freshly updated timelines. However, due to the previous problems, users of our SMS service may experience some missing tweets.
