Ticket Description: Scheduled upgrade of EPFL access links to SWITCHlan
Scheduled Starttime: 2021-06-08 06:30:00Scheduled Endtime: 2021-06-08 08:00:00

Problem Description:

New 100 Gb/s access links between EPFL and SWITCHlan will be put into service, replacing the existing 10Gb/s links.


From 2021-06-08 06:30 until 2021-06-08 08:00
Impact: no more redundancy
Service: network access
Sites: EPFL

During the activation of the new access links, traffic will be switched between primary and backup interfaces. This could cause short interruptions and possibly blocking of ongoing connections.


2021-06-08 08:00
The access was successfully moved over to EPFL's new 100G-capable campus perimeter infrastructure in several steps. There was a brief interruption of traffic between 06:34 and 06:45.

Both the active (primary) and backup (secondary) links are now at 100 Gb/s. The old 10 Gb/s links are still available as a fallback. We will observe the new connection for several days/weeks before cleaning them up.

All times are in local Swiss time CET / CEST.
