It looks like problems on Twitter that began Friday night are persisting Saturday morning. People on the east coast of the US were reporting that while the page would load, they were unable to send tweets and DMs. Twitter Support posted a brief message Friday night that it was looking into the matter
Tweets may not be loading for some of you. We’re working on fixing a problem and you’ll be back on the timeline soon.

Donwndetector, which monitors site outages, showed a massive spike in problems around 8:25PM ET on Friday. Things seemed to be returning to normal within an hour, but Saturday morning around 8AM ET, it was showing a small uptick in reported problems again. Often these outages are the result of a problem with an intermediary service like Amazon Web Services, but its dashboard shows all green as of this writing. And Twitter’s API status website was showing no problems this morning, either. At least, not yet.
There’s no official word on what is causing the problems and if it’s still limited to the eastern US. We’ve reached out to Twitter for more information and will update when we know more.
