Update:  Since Linkedin came back up, I have lost 3 million people from my network while my 1st degree contacts stayed the same. Also, 2 new cities have taken over as the leading regions. How does this happen? Was it broken before and fixed now or working before and broken now?

Update 2:  Since my last update, I ran across this. It seems that Linkedin is taking a more aggressive stance against users with lots of links. Many of these users have seen their networks mysteriously shrink. There’s a conflict between Linkedin’s philosophy of only linking to people that you know and the philosophy of “open networkers” that link to as many people as possible. Looks like my shrinking network was deliberate and not an error.
