philadelphia public internet exchange?

What's the situation with the philadelphia internet exchange? Their
website, does not resolve. Google is sparse. Anyone have
any information regarding that IX? Is it gone? If it's gone, what are
some viable alternatives for public peering in the philadelphia area?

I started the project back in the mid/late 90s with big plans and
dreams, but was never able to get enough other people interested.
I'm no longer in the ISP business, and let the domain registration lapse.
