eBay powered by Sun?

I was checking out my auctions on My eBay (UK)  when I noticed a “Powered By Sun” logo next to the eBay logo. I clicked the logo and got the following message:

Powered By Solaris, the operating system the world trusts
Powered By Java, the world's preferred platform
Powered By Sun Systems running SPARC processors
Powered By Sun services and solutions
Sun helps to power eBay’s Global Marketplace.

eBay has chosen Sun's Solaris Operating System and its suite of low-cost Solaris servers and Java software to help power the The World’s Online Marketplace. If you're running a business like eBay's, or have similar aspirations, get some Sun.

This stuck me as strange as the url is http://my.ebay.co.uk/ws/eBayISAPI.dll?MyeBay
Unless they pulled some strange tricks it is an ISAPI DLL which means the system is running a Microsoft IIS server.

To find out if it was crap or fact, I fired up Ethereal to have a closer look.  Guess what.... eBay is still running Microsoft IIS 5.0 on Win2k for the main features; catalog details, bidding, my eBay. These are some of the headers from My eBay (cookies etc removed):

Some of the static stuff like the home page has been moved to Sun though.
