New Delhi: Twitter users worldwide were unable to access the micro blogging site on Thursday with an outage that affected both mobile and web platforms. The US social media giant experienced the second service outage in a little over one week where the user were unable to log onto the platform.

Twitter has been undergoing some problems since 2:46 p.m. (according to Eastern Time)  and more users were alerted with a message saying "something is technically wrong" when they tried to log on, the Xinhua news agency reported.

"IS TWITTER DOWN OR IS IT JUST MINE," asked Twitter user mica@kianscloudy in a tweet, which followed with replies from many users who responded with the same problems.

The service interruption was confirmed on Twitter's status page, which said there was an "active incident" that affected the platform's normal operation.

However, after 2 hours, the issue was fixed by the social media techie. The Twitter’s support account in a tweet later informed, “Twitter is back up for some people, and we’re working to make sure our service is available to everyone as quickly as possible.” The company said the outage was “due to an internal system change, which we’re now fixing. We’re sorry for the inconvenience and should be at 100% soon.”

It was the second time that Twitter reported widespread outages in more than one week after the firm experienced issues with DM delivery and notifications on July 3.
