[outages] ultradns issues? unable to resolve amazon.com

[dl]

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.
