Update #3 - Final Update: Guam 1
and 2 returned to normal operations as of 1/20-2210Z. Both
LUTs have processed six satellite passes without issue. All
missing data has been recovered.
Update #2: The ticket has been
referred to the back bone group to investigate the trunks.
The LUT Vendor informs they have two way traffic, however,
LUT
data is being received intermittently and they will continued
to be troubleshooted until the circuit is fully restored.
Update #1: There is a new Guam circuit that is
still in
provisioning that will move the circuit to a new path. The
Verizon repair team believes that the move will resolve the
ongoing issue with the circuit. They also report there was
extensive circuit testing done over the last week to test the
T1 to the site and this may have caused the bouncing.
Counters have been cleared on both sides and is being
monitored for errors. Since the USMCC has reported the
circuit now down hard, the ticket is back with the repair
team
for further investigation.
