What happened to www.IdAuthority.com? Comodo's links do not work

Comodo’s links to “IdAuthority” or www.idauthority.com on Comodo’s Web Identity Assurance webpage are dead.
To get to this webpage:
From Comodo’s homepage choose Products then Web Identity Assurance. All of the IdAuthority links are on this page.

My understanding is that Comodo operates the IdAuthority, “the largest directory on the web with identity assurance details on over 15 million websites”, direct quote from Comodo’s Web Identity Assurance webpage.

Can’t get to it for details on this service.
