Hi,
	Yeah, I was just seeing some issues through TATA (AS6453) with routes
being blackholed in Newark, or at least that was where the packets
stopped. I had to shut my peer with them and I just finished opening a
trouble ticket.

A traceroute to 209.167.35.0/24 from a source addr in 205.211.164.0/24
byte packets
 1  teleglobe-vl38-tor (205.211.165.121)  0.259 ms  0.465 ms  0.488 ms
 2  if-2-3-513.core4.TNK-Toronto.as6453.net (209.58.16.21)  0.987 ms
0.981 ms  0.565 ms
 3  if-14-0-0.mcore3.TTT-Scarborough.as6453.net (63.243.172.2)  53.390
ms  2.973 ms  2.991 ms
 4  if-3-1-0-0.tcore1.NJY-Newark.as6453.net (216.6.98.34)  20.481 ms
62.938 ms  20.967 ms
 5  if-2-2.tcore2.NJY-Newark.as6453.net (66.198.70.2)  20.986 ms  21.059
ms  20.871 ms
 6  * * *

Not sure if it was after them or coming back to them.  Same source addr
through AS174 is fine
