Sounds like theres some murmur on nanog about this too. ; <<>> DiG 9.6.0-APPLE-P2 <<>> amazon.com @ns1.nyc.pnap.net ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 20214 ;; flags: qr rd ra; QUERY: 1, ANSWER: 3, AUTHORITY: 6, ADDITIONAL: 8 ;; QUESTION SECTION: ;amazon.com.

Seeing problems trying to reach amazon.com. Looks like the ultradns name servers aren't responding? at least from here, and other external dns servers I query can't seem to resolve amazon either.
Friend of mine still has some of their DNS in cache, and hardcoding dns in my hosts file allows me to hit Amazon without any issue. I was surfing fine until my DNS flushed and couldn't re-resolve.
Anyone else seeing anything fun?
Looks like they might be coming back online - my trace is actually making it to them now, sort of.
