Interesting post and stats over on www.iss.net www.iis.net. Microsoft.com has now migrated all but one server over to IIS7. 99% of apps worked unchanged. Most folks don't realize this but Microsoft.com has the 4th widest audience in the US and the 5th widest worldwide. The site runs primarily out of two data centers on 80 web servers.
It is actually www.iis.net, not www.iss.net.
This is interesting information. I am curious how many hits a site like microsoft.com gets per day....
