Yahoo DNS broken?

[larryd at iservetech.com (Larry Daberko)]

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.

Interesting, as my nslookup..

> www.yahoo.com
Server:  ns1.hostremote.net
Address:  66.187.130.31

Non-authoritative answer:
Name:    www.yahoo-ht3.akadns.net
Address:  209.191.93.52
Aliases:  www.yahoo.com

And yes, I can hit http://www.yahoo.com in a web browser. Works for me.

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

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 :-)
