Twitter users can rejoice now that the social networking service is up and running after a bug caused a partial blackout.

The San Francisco-based company said the bug, which was in its "front end code," prevented users from signing in to Twitter, and that the problem was now fixed, according to Business Insider.

"We apologize for any inconvenience," Twitter said.

The issues took place from 4 p.m. to 9:25 p.m. (PST) and included irregularities with the Twitter app for Android and iOS smartphones and tweets on the computer app TweetDeck appearing as having been posted a year ago.

"Something is technically wrong," Twitter's welcome page read during the blackout. "Thanks for noticing- we're going to fix it up and have things back to normal soon."

The blackout is the latest incident in which a large company experienced issues online, with others including the hacking attack on Sony that resulted in a massive loss of data, Business Insider reported. The U.S. has placed the blame on North Korea, which has been displeased with Sony's release of "The Interview," a comedy film that centers on the assassination of the country's leader, Kim Jong-Un.

Twitter has also managed to obtain 284 million active users at the end of September.
