Twitter has admitted that some users of the micro-blogging site were unable to access their account.
Users originally started complaining that Twitter was running excessively slow or not at all on multiple platforms. Complaints were eventually backed up by an official Twitter posting which admitted the site was having issues.
At the time of writing, Twitter has reported that the outage has been resolved.
"We experienced intermittent issues affecting web and mobile users, globally, between approximately 7:00am and 9:50am PST," Twitter wrote.
"This incident has now been resolved. We apologise to users who were affected by this, and we're working to ensure that similar issues do not occur."
The downtime marks Twitters second string of issues in the last month. During President Obama's second term inauguration last week. Twitter went down due to the high volume of users tweeting about the event.
V3 reached out to Twitter but the company has yet to give any details on the exact reason behind the service outage. Twitter was also unable to give an estimate for how widespread the outage was.
The recent outage comes following the company's launch of the social video tool Vine. Twitter's new tool allows users to shoot short video clips and upload them to their feeds. Vine also suffered issues at launch.
