Re: NTT->HE earlier today (~10am EDT)

NTT's customer Sofia Connect leaked our routes to NTT.  NTT accepted 
these routes instead of properly filtering their customer 
announcements.  As a network of non-trivial size, announcing over 75,000 
customer routes which is nearly 15% of the IPv4 routing table, we'd 
expect the common courtesy of having our ASN included in their customer 
facing AS-PATH filters, as we extend this same courtesy to other 
networks of this size (such as AS2914).
