Business networking site LinkedIn was down on Wednesday morning, with the company telling its users to "sit tight" as its team needed to "clean things up." As of 10:25 a.m. EDT, we do not know the cause of the outage, but LinkedIn formally acknowledged the service disruption over Twitter earlier this morning.

Our site is currently experiencing some issues. Our team is continuing the work on this. Stay tuned.

Prior to the formal message by LinkedIn, users that tried to access the site received a "Gateway Timing Error." We've reached out to LinkedIn for more information, and we'll update this story as soon as we learn more.

Social networks are not immune to service disruptions: Even after roughly three months without a hiccup, the Fail Whale re-emerged when Twitter went down for a brief period of time on Jan. 31.

LinkedIn boasts 200 million members in more than 200 countries and territories around the world.
