Millions of users worldwide complained that they were unable to send tweets and lamented that their homepage feeds went blank during the inexplicable interruption which began at around 10.30pm on Thursday.
Sometime after this began, Twitter issued a statement that it was working to resolve the issue and did not believe that it was as a result of a breach of Twitter security or a hack.
Over a period of 2 hours, the app intermittently came on and crashed again.
Yesterday, Twitter temporarily blocked President Donald Trump’s re-election campaign’s account after it posted a video about Democratic presidential candidate Joe Biden’s son that it said violated its rules.
