Facebook Inc. restored services after some users couldn’t access the largest social network due to possible technical issues, two months after another major disruption.

Earlier Friday, Facebook wasn’t working for both mobile and Web browser users. On Twitter Inc.’s service, #facebookdown was a trending topic in the U.S., according to the microblogging company.

Facebook has grappled with service issues in the past as it seeks to keep its more than 1.3 billion users connected on mobile devices and desktop computers. In June, members in cities such as Tokyo, London, New Delhi and Moscow couldn?t access the site for about 30 minutes.

Some people had trouble accessing Facebook for a short time, Jay Nancarrow, a spokesman for Menlo Park, California- based Facebook, said. "We’re sorry for the inconvenience."

The shares of Facebook fell less than 1 percent to $72.36 at the close in New York, leaving them up 32 percent this year.

Service problems affect a wide swath of Internet companies. Last year, Google Inc. said a disruption affected a "significant subset" of users for its online storage feature. Later in 2013, Yahoo! Inc. Chief Executive Officer Marissa Mayer apologized after some people had trouble accessing e-mail.

The Facebook Web outage came after the company reported rising sales as users increasingly access the service and advertisers spend more to reach them. Last month, Facebook said second-quarter revenue surged 61 percent to $2.91 billion, exceeding analysts? average estimate of $2.81 billion.
