Ticket Description:	Scheduled 400G upgrade CE (6.-8.12.2022)
Scheduled Starttime:	2022-12-06 12:00:00	Scheduled Endtime:	2022-12-08 12:00:00

Problem Description:

We will upgrade the optical system and one of the routers in CERN to 400G.
During the upgrade, each redundant service will be migrated to new equipment in turn. At all times there is at least one path available for each service.

Each impact will only be active for a few minutes, no total loss of services is expected.

Affected:

From 2022-12-06 12:00 until 2022-12-08 12:00
Impact: no more redundancy
Service: P2P/OPN
Sites: BELWUE-KIT-CE, CERN-EQUINIX, EXOSCALE-GEANT, L2VPN-RKAU-INDIANAPOLIS, L2VPN-RKAU-SANTACLARA, L2VPN-RMUE-INDIANAPOLIS, L2VPN-RMUE-SANTACLARA, SYNGENTA-INTERNET2, SYNGENTA-JANET


From 2022-12-06 12:00 until 2022-12-08 12:00
Impact: no more redundancy
Service: network access
Sites: CERN, GEANT AP1, HESSO-HESGE, HUG, RKAU, UNIGE

Actions:

2022-12-08 10:59
All work could be completed as planned. The new 400G/s links CERN-Zurich (ETH) and CERN-Lugano (CSCS) are up and carrying traffic. Both PoPs at University of Geneva are now connected in a 100Gb/s ring with other SWITCHlan backbone sites.
