RE: Yahoo DNS broken?

["Paul Stewart" <pstewart () nexicomgroup net>]

I talked to Yahoo! NOC a little while ago and they are working on the
issue - definitely DNS related and appears to possibly be east coast
only.... details are vague but they are aware of it and no ETA yet...

There is no A records, correct.
There is a CNAME though:
www.wa1.b.yahoo.com.    45      IN      CNAME   www-
real.wa1.b.yahoo.com.
www-real.wa1.b.yahoo.com. 45    IN      A       209.131.36.158
