Thousands of Twitter users complained of problems on Friday evening, the third time in a matter of days that the popular microblogging site has suffered an outage, Telegraph.co.uk reports.
Users in the UK, France and across the United States all said they had experienced difficulties posting messages or viewing their timeline.
Twitter confirmed the problem and said it had resolved the issue.
"Earlier today, people were unable to send Tweets for about 30 minutes," it said on its Twitter Support account. "We’ve resolved the internal issue and we’re sorry for the disruption."
As with previous episodes, users still managed to make their feelings clear.
