Social media site Twitter says it has resolved a problem which prompted it to crash, causing problems for users across the world.

“We are continuing to monitor the issue, and things appear to have returned to normal,” the company said in a statement.

“For streams, if your connection was maintained during this period, you should have received available data since this issue also affected the publishing side of Twitter. If you disconnected at all, a Replay will recover any Tweets during your disconnect, and the volume is likely to be very small.”
