What to do when your host goes AWOL

Hi
I'm hoping you may have a way for me to contact my web host. Strange thing to say I know. You see our host has gone AWOL and so have our major money-making sites. For over 2 years we have had a great relationship with Kenneth Fox from Windy City Web Solutions. The service was so incredible we transferred all our sites to him and referred all our customers to him. In the last few months service has really dropped but we cut him some slack because we knew he has some illness in the family.
But 3 days ago one of his servers died. With it has gone all our major money-making sites.
Short term problem? We thought. Until no emails responded to, support desk not responding, skype ignored and telephone disconnected. Their other server with our other sites is functional though. I'm not sure if they are going out of business, stopped caring or if they will be back on board. Meanwhile we have the decision to make about recreating sites from backups - big database driven sites that is! I'd much rather get the sites back up again so I can do a server to server transfer to a new host.

So my question to you: do you know if anyone else has been affected by the problem with Windy City Web Solutions? Do you know any way to contact the host? I've tried:
email: no response
Help desk: no response
phone: disconnected
Skype to kennethfox: no response
twitter @kennethfox: no response
facebook / KennethFox: no response
DM through here: no response even though he was active here while our sites have been down?

I'd really appreciate any help you can give. Either a way to contact them or any info on what is happening with their business.
Cheers
Janet
