It seems that Snapnames is still working on the problems. When you search for domains using the advanced search or search box, you get warning about a certificate expiring:

This is really quite strange as Overture belongs to Yahoo. When you visit the link you get:
To VIP Status: OK
Server Status: OK
The title tag changes to “Hello from Apache :-)”
and then it diverts to the Overture Small Business website. Perhaps Snapnames has included some Yahoo code somewhere?
