Actually it's still up.
About a month after the shutdown, it was turned into an open/free network with no tech support or guarantees. Turns out that it's a lot cheaper to run a network when all you have to do is keep it up and not support the end users, collect payment, process signups, etc. I like it this way better. What EarthLink was running only cost a little less than Comcast and Verizon, so I didn't see much point to it.
