my setup: linux/redhat name servers bind-9.3.6-4.P1.el5_4.2
beginning yesterday i'm seeing something i haven't seen before. if i do this (for example): # dig weather.gov +short ;; connection timed out; no servers could be reached and then immediately do this: # dig weather.gov +short 140.90.113.200 the first line takes a while to fail. i do an up arrow and return, and the second command responds instantly. MOST THINGS ARE WORKING FINE. i've only found two addresses w/ this fail-then-work problem. the other is rs.dns-oarc.net i'm being told this is a problem with their name servers; in the specific case of dns-oarc.net i find that particularly hard to believe. once it works it will continue to work if i keep doing the command rapidly. if i let it sit for a while, then i can get the failure again. that's probably my cache doing the right thing. what i can't figure out is this fail-then-work behavior. oh, i've checked the logs. there's zillions of messages about notifies and transfers. once i clean those out, i don't see anything interesting at all. now i'm also getting this: (the first response doesn't have answers, the second does. but i'm NOT getting "no servers....") # dig weather.gov ; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2 <<>> weather.gov ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 35953 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;weather.gov.
