I and customers are having random issues resolving .com.tw domains this morning. When I dig +trace, for the longest time f.dns.tw would not give me an answer other than an SOA. Now I am getting NS answers again from f, but g.dns.tw is doing the same SOA only answer. I can't get a connection to e.dns.tw at all (though it seems like it's a local negative cache issue b/c if I query the IP for e I get from the root servers, I get answers back).
What's not working: [todd@tlyons ~]$ dig com.tw @g.dns.tw ; <<>> DiG 9.7.3 <<>> com.tw @g.dns.tw ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 50495 ;; flags: qr aa rd; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; WARNING: recursion requested but not available ;; QUESTION SECTION: ;com.tw.
