[outages] CloudFlare - ipv6 issues ?

[Brandon Applegate]

Hmm, there may be MTU issues, but I think I have just routing problems to 
start.  All of my traffic is going to go out Level3 (at least right now). 
Doing a trace from level3 (Cincinnati - which is where our circuits come 
from) results in timeouts:

Guess I should open a ticket upstream and maybe have Level3 poke 
Cloudflare ?
