They've been using onion domains to provide service while their clearnet site is unavailable - so the technical solutions do indeed exist. They're just harder to use.

Of course, the other option is to find someone who does want to host you or start your own. They've done decently, bulletproof.al has been willing to provide them domains, bitmitigate is providing their DDoS protection, etc.

As others in this thread have mentioned, there's a tendency for many entrepreneurial types to gravitate towards services that are very much hands-off, BitMitigate and Bulletproof made a name for themselves here and I'll certainly give them a shot if I'm hosting anything where users can post comments or I'm posting things that are remotely controversial. There's value in knowing your site won't go down even if the worst kind of controversy is stirred.
