Haha fugazi...
I've been playing this game since early beta and I think in all that time, the host has truly crashed for more than a few minutes maybe twice. That's a pretty damn good record. Say whatever you like about AH compared to other games, but HT's server code is pretty damn good by pretty much any standard. HT and crew are consistently making better use of current technology and their hardware/cash limits than other online gaming services out there.
Do a search on the BBS for server crash or mass dumps, whatever, and you'll probably find maybe a dozen in the last several years. That's just a couple per year, not too bad, and you'll also find that not many of them are caused by problems at HTC. It's usually a network issue they have no control over, or a new version has problems and they fix it immediately.
