Our site has completely vanished from Yahoo SERPs since the switch.

A search for "www.mysite.com.au" returns nothing... however a search for "mysite.com.au" returns several listings under an old subdomain no longer in use - since replaced by a redirect.

In short, "www.oldsubdomain.mysite.com.au" is indexed, however "www.mysite.com.au" is not.

"www.mysite.com.au" has a Y! directory listing and plenty of links pointing to it from other indexed sites as well as ink PFI listings.

Is this drop a penalty based on Y! believing that our original site is duplicate content of the old subdomain redirect site?

I can remove the subdomain all together, however it will mean that the yahoo listings we have would cease to work. Please help, have exhausted my brain trying to figure Y! out!
