Yahoo DNS broken?

[cmills at accessdc.com (Mills, Charles)]

Their other pages (finance.yahoo.com) and such seem to resolve ok.

Wondering if it isn't part of a bigger problem because I got a complaint
that many sites
Were unreachable for a bit.

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 :-)

but looking up the host itself gives no answer
