I love NatNet too
Been with them for like 5+ years. Recently tried a new project and got hosting elsewhere to save money since NatNat can be a bit higher priced. Worst decision ever! Am too spoiled by NatNet support which makes my secondary host look like total crap.
All support from this "other hosting company" including setting up new domains takes up to 2 hours or more. Have a friend who's there #1 client and gets fantastic support straight from the owner. Owner has no idea who I am or what I really run elsewhere so I get basic low end support filled with excuses when things aren't done right.
Am going to cancel that host and move it all over to Natnet 100%. This other hosts "top tier" support is what NatNet gives all their clients.
In summary NatNet gives small under $1K monthly accounts better support that $10K+ monthly accounts on other host. Natnet all the way.
