ESnet,
We have intermittent connectivity problems between Jefferson Lab
(jlabs1.jlab.org) and the University of Richmond (psc1.richmond.edu):
----psc1.richmond.edu PING Statistics----
105 packets transmitted, 42 packets received, 60% packet loss
round-trip (ms) min/avg/max = 79/82/89
----psc1.richmond.edu PING Statistics----
14 packets transmitted, 11 packets received, 21% packet loss
round-trip (ms) min/avg/max = 80/82/89
Could you take a look?
Thank you,
Sandy Philpott
