Site doesn't load on IE 6. I wonder if you've configured the SSL certs with SNI? Would have been nice to see the page turn red, but I guess I know the answer without having to run it...
Edit: It's not an SNI issue, IE 8 on XP can load the site.
MSIE6 does not support new enough SSL to be considered secure. I wouldn't be surprised if a lot of sites no longer work with MSIE 6 over the next two years as sites transition to turning RC4 and SHA1 off.
We all know this. My point is, the site gives some indication as to how effective any particular browser's SSL is, yet the site doesn't function for the worst offenders.
