Thanks to the folks at Netcraft I've just found out that Microsoft.com is putting it's webpages where our mouth is and running on Beta3 of Windows Server 2008 and IIS7 (and appears to have been doing so for most of June).

Now that "the server formerly known as Longhorn" has a Go Live licence you could join the 2500+ sites who are already trying this out for real.

Obviously before making the switch from Linux/Apache or an earlier version of IIS you'll be keen to find out what the new platform offers... well, a good place to start is the IIS.NET article on what's new in Longhorn Server Beta 3 ... as an extra goodie that page has links to a number of providers offering free hosting so you can try it out and see how your current applications work and how performance compares...
