Scheduled cutover from 100G to 400G on the Montreal–Amsterdam circuit, which currently carries LHCOPN circuits:

Primary Link to CERN [VLAN 2127]
IPv6 Link to CERN [VLAN 2126]

Please note that VLAN 2128 via New York (LHCOPN through MANLAN in NewYork) will remain up during this activity.

The outage is expected to be very brief as the circuit is up.  Software commit change only.
