johnmccain.com and barackobama.com are both registered with GoDaddy, but McCain appears to have registered through GoDaddy India via Domains By Proxy… (Why does his campaign need to use Domains By Proxy, which is designed for anonymous domain registration? Maybe they just love outsourcing?)
JohnMcCain.com has been around since 1998; BarackObama.com since 2000.
McCain uses IIS running on Linux (?). Obama uses PWS running on Linux.
And the running mates? joebiden.com has been around since 1998; sarahpalin.com is not owned by the campaign, but is registered through the same proxy company as McCain.
Sarah runs Linux with Frontpage extensions (yeuch!); Biden’s running Apache.
IIS on Linux? Erm…
Ah… Netcraft explains it can be due to proxies and servers running different things.
