Someone on echo pointed out that eBay has switched from IBM technology (servers + WebSphere as I recall) to Sun. The URL for the powered by link still reads http://pages.ebay.com/ebay_IBM.html but it links to a page reading:

eBay is Java© Powered
Running on powerful Sun
Solaris© SPARC® servers
Supported by Sun services and solutions

eBay has chosen Sun’s Solaris Operating System, the most advanced operating system on the planet and its Solaris servers and Java software to help power The World’s Online Marketplace. If you’re running a business like eBay’s, or have similar aspirations, get some Sun.

Now, it's possible it's a glitch, but given that the graphic has changed as well as the text, it appears that IBM has lost a major reference customer for WebSphere and DB2.

Of course, as we're no longer an IBM family I don't really care.
