Yes, currently it is only ATT customers. @home used to rent out it's servers to ATT and several other companies, like Cox or Comcast. But ATT also had several other internet services...like worldnet...which I think is dial up....and they have MediaOne...which is a cable serviceor at least they did...many of those customers were converted before @home cut them off. Now ATT has ATT broadband (I think it is called)

I still have no idea what is going to happen to the other @home customers...whether they will eventually lose their service or not...I do not think anyone really knows right now...
