Oops! LinkedIn Goes Down, Can’t Get Up

LinkedIn may be profitable and growing fast , but something seems to be going very wrong with the business social networking service today. The service has been going up and down all day over here in Europe, and has now been displaying an 'Oops' page for the past 55 minutes (4:30 PM CET). Update: it's back up, downtime lasted exactly one hour. Update 2: and it's back down again (4:45 PM CET), they're having serious technical issues over there. Update 3: it's bouncing up and down. Seems to be stable now (4:52 PM CET) It's a very unusual thing to happen with LinkedIn, which has always had quite a reliable web service, and there's no official update to be found on the LinkedIn Blog (which is still up). Meanwhile, Twitter users are spreading the word about its current downtime fast.
