Here is what I get when I try and change my password:

  Page not available
  Ebay is asking its users to reset their passwords due 
  to the unauthorized access to our corporate information 
  network. This may result in a delay of service due to 
  the high traffic volume. We ask for your patience and 
  that you return to eBay soon.

I wouldn't think that "password changes" were really that heavy a function.

Edit - Finally got through. They are not letting you change your password directly, you either need to respond to an SMS or Email. Probably a (very) good idea if they are worried that someone has done a bulk theft of passwords.
