Yes, I am now seeing the akadns.net address. Looks like went through
some fluctuation there, but the site is back up for me now. There is
also a report on the outages list.

Yes, www.yahoo.com is unreachable for me too, but mail.yahoo.com and

Subject: Yahoo DNS broken?
I am unable to resolve www.yahoo.com. Tracing DNS back from the root
servers shows that www.yahoo.com is a CNAME to www.wa1.b.yahoo.com and
there are no A records for that hostname.
Anyone have more details or a Yahoo contact? I'm unable to get to their
webpage as it is :-)
