Hi John,
Although there are still some packet losses, this looks much more

sees this as well & continue to monitor for 24 hours before closing our ticket.
Thanks, John.

Sandy, excepting the 3% packet loss that may be congestion at the University of
Richmond end, does the problem look OK from your end now? Please let me know by
