Yes, www.yahoo.com is unreachable for me too, but mail.yahoo.com and login.yahoo.com are up. -----Original Message----- From: Larry Daberko [mailto:larryd@iservetech.com] Sent: Wednesday, December 03, 2008 3:37 PM To: nanog@nanog.org 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 :-) -Larry Daberko iServe Technologies $ dig @ns1.yahoo.com www.yahoo.com ; <<>> DiG 9.4.2 <<>> @ns1.yahoo.com www.yahoo.com ; (1 server found) ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 56431 ;; flags: qr aa rd; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2 ;; WARNING: recursion requested but not available ;; QUESTION SECTION: ;www.yahoo.com.
