Re: UUNet/Telia peering problem...

Craig,

I cannot see that this route should go through concentric/xara.net/xo,
nor indeed that it does.

Possibly something's been fixed.

Tracing the route to yahoo-inc-gw.customer.alter.net (157.130.252.102)

Trace from thor.europe (same network as the tunnel router) to
157.130.252.102 go through xo/concentric net
^^^^^^^^^^^^^^^^^^^

if this meant you are using LSSR or something (for some reason)
to use xo/concentric:

telehouse29>trace 157.130.252.102

Type escape sequence to abort.
