Twitter.com was unavailable on Monday for some users across the United States, but the site was restored around 3:15 p.m. EDT, Twitter said.
Twitter Inc said users experienced problems accessing the service between 2:22 p.m. to 3:16 p.m. EDT, but the mobile app and Tweetdeck, which allows users to view multiple Twitter browsers at once, were unaffected.
Twitter users and others said they received a message that read "something is technically wrong" when trying to open the Twitter website on their personal computers.
