Micro-blogging site, Twitter, experienced a global outage today. The site first went down just after 10 a.m. Eastern Time for most users. Twitter confirmed that the site was back up and running normally at 12:50 p.m., meaning that the outage lasted nearly three hours.

"We apologize to users who were affected by this, and we're working to ensure that similar issues do not occur," the post reads.

For almost the entire first hour of the outage, Twitter was inaccessible to nearly every user worldwide. Most users who attempted to access Twitter during the outage received the typical fail whale message that "Tiwtter is over capacity." Some users, however, saw the newer "Something is technically wrong" screen, which includes an icon of a robot missing a claw.

North American users reportedly regained access to Twitter shortly before 11 a.m., so the downtime was not as long for US users. It's not clear what the cause of the issue was, though Twitter is said to be working on fixing it so that similar issues don't occur.
