Yahoo! account registration fail

I tried to register for a Yahoo account (intending to use Flickr) and when I tried to log in, my account did not exist. I went back to the registration page to try again (saying yes when asked if I wanted to re-send the form) and the password and custom security questions were understandably blank. However, the country had also changed from Canada to Cambodia.

I tried to recover my Yahoo! ID using my other info, and it said no such account was registered. This would probably have been much easier had a confirmation email been sent to my alternate email address.

This affects all services because I cannot create an account.
