routing issues to AWS via 2914(NTT)

Amazon hasn't reached out to us either...

If you have other providers, use a combination of local-preference and the
customer communitiy strings with ntt to prepend around the circuit(s) in
nyc with the issue.  Just check your routing table, we found many going
through ntt to amazon and took awhile to get everything working as desired.
