Ok without disclosing to much about their online setup
I am pretty sure that the forums are hosted by secure servers in arizona running through cloudflare to protect this site from DDOS attacks and to hide their ip address.
Linusmediagroup.com is hosted with squarespace.com which I think used AWS (Amazon Webservices) for web site hosting/servers
Well that a bit boring, I just went to the hassle of Resolving their CloudFlare protected domain to find their true domain name, to try and see were it's hosted
