End of Transport for OS X Lion?

I had one machine go out using OS X 10.75 Lion about six month ago. Today, the final 3 machine that are on Lion disconnected from the Transporter servers. Why? These 3 machine were running just fine and something change on all the machine at once. I find it kind of odd that I registered for this forum just yesterday, and the support for my Lion machine were cut off on the same day (after I registered) within a few hours. Hummmmm.

Does anyone have Transporter still syncing on a old machine using Lion?
