LinkedIn's Web site went down at least three times this morning due to an unknown issue.
The company confirmed the problem in a Tweet today. The site was up and down all morning, and is currently down again.
LinkedIn earlier posted an image telling users that it was "taking a moment to clean things up." The site returned shortly after its first bout of downtime, but certain features such as the in-box were unavailable. A second error message an hour later noted that there was a "Gateway Timing Error."
A LinkedIn representative told CNET that the Web site is back up and running.
Updated at 7:25 a.m. and 8:57 a.m. PT: The site is back down after it was briefly restored.
