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

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
