BT operate 2856 in the UK, and 5400 internationally

5400 used to be concert which was a BT/ATT venture which is now solely run by BT 
under their brand - hence I guess why the msg on concert.net

Email contact sent offlist..

Grrr....Three days later, BT is now telling their customers that 
somehow, this is our fault. I find it rather odd that everyone in the 
world can reach us, *except* BT customers, yet it is our fault.

NB, this only affects some of our address space (I received one 
confirmation report that another AS is also affected by this). I have 
tried four different peers, and it doesn't make a difference where I 
send outbound packets.

I have sent mail to every address @BT that looks like it might possess 
clue, to no avail. This is a general plea for help- if anyone has an 
idea of how I might resolve this, I would be very grateful...

 From inside BT, looking at one of our clients colo'd servers:

Well, no duh.... Going to www.concert.net I read "Concert, the AT&T and 
BT global communications venture, was legally closed on 1 April 2002".

Ok, so WTF are they sending packets for us that way then???
