Business networking site LinkedIn was down on Wednesday evening, with the company telling its users to “Keep Patience” as the team continues to solve the problem.

LinkedIn has formally acknowledged the service disruption for some users over Twitter. Here is the tweet posted by the company’s official Twitter account:

1st tweetSome members may be having trouble accessing our site. Our team is investigating. Stay tuned for updates.

2nd Tweet (embedded):

10:31 PM EST:  The business networking website is still down and many users are still unable to access their accounts. Stay tuned for more details.

Bryan Berg on states:

LinkedIn just got DNS hijacked, and for the last hour or so, all of your traffic has been sent to a network hosted by this company []. And they don’t require SSL, so if you tried to visit, your browser sent your long-lived session cookies in plaintext.

UPDATE 11:45pm EST: The website is back up.
