Status of Inerail?

Does anyone know the status of Inerail (AS33031)? All of their ASNs and prefixes disappeared on 9/1/2015 according to http://bgp.he.net/AS33031 All of the contact emails I found seemed to have been hosted under the ASNs and prefixes attributed to Inerail which are now gone from the Internet. I was looking for information on the Philadelphia Internet Exchange which I think they are/were running.
