Bad net to Maui

[Margaret Lewis]

Bob,

Been talking with the Maui networking folks and they seem to feel that some of
th problem we experienced during this session last Friday was the fact that this
session might have been routed over our ANS T3 line (we have two T3 lines -- one
is DREN and one is commercial line we purchase from ANS). These lines back up
each other in case of problems -- so there is always a chance Access Grid
sessions will go over ANS.

With this in mind is it possible to set up the routing for ANS (as we did with
DREN) so that we get the best path possible for Access Grid use?
