Chapter 11 isn't neccessarily the end of the company. I know two very large engineering companies (amusement ride design and construction), that in the last year have both declared Chapter 11 or their nation's equivalent (one was in The Netherlands) of bankrupcy protection.
That's primarily what it is, a company files for Chapter 11 for protection of their assets and ongoing lawsuits while they restructure and try and get their finances fixed.
Often, not much happens, the company disappears. However, in my previous two examples, both companies are slowly coming back (one was the largest producer of rollercoasters in the world, the other invented the modern steel rollercoaster).
I have no idea with this company, but your best bet is to wait it out. If you're getting the service, you should continue paying, or cancel your servers and discontinue payments.
The last thing I'd do, if I were the operators of this company, is withhold information from the clients. I don't know who's running this, but I'd expect that before you find your server offline, you'd at least be told something.
