Just as Google was able to restore service to Google Talk, Twitter has gone down for many users. The company acknowledged the issue on its site status page, saying that engineers were working hard on a fix. There's no word on when it'll be back up, but this marks the second major service interruption for the site in the last month. There's a small ray of hope, though — we've successfully sent out a tweet through Twitter's mobile site. If you desperately need a fix, feel free to give that a shot.

Update: While Twitter's official status blog hasn't been updated yet, we're seeing service coming back to live both here in the US and across the pond in the UK, as well.

Update 2: Twitter has updated its blog with an apology and an explanation for the outage. Two data centers went down "at nearly the same time," wrote Mazen Rawashdeh, VP of engineering. "I wish I could say that today’s outage could be explained by the Olympics or even a cascading bug. Instead, it was due to this infrastructural double-whammy."
