Only systems in the US which have an IPv6 address which take the
following AS path seem to be affected (1273=>C&W to 1103=>SURFnet):

2001:610::/32      *[BGP/170] 01:06:34, localpref 70, from 2001:468:c00::251
                      AS path: 1273 1103 I
                    > to fe80::205:85ff:fe6f:ff70 via xe-7/2/0.0

If a host only has an IPv4 address, there will not be a problem.

As Ronald suggested, I think it would be best to find out what is
happening inside Cable & Wireless -- it appears to be their problem..

It is clear (from the Internet2 router proxy) that the following AS
path works fine (20965=>GEANT2) -- I'm convinced it is a SURFnet
problem.  :-)

2001:610::/32      *[BGP/170] 15:45:45, localpref 100, from 2001:468:9::1
                      AS path: 20965 1103 I
