Title: Cenic Network Maintenance, 6/27/11-6/30/11, 10pm-6am Nightly
Description: SDSC may experience brief outages as traffic shifts back and forth as circuits are disabled and re-enabled.
Please see below:
This message is to alert you that the CENIC network
Engineering team has scheduled an Optical Route Upgrade:
START: 2200 [PST], Nightly 6/27 – 6/30
END: 0600 [PST], Nightly 6/28 – 7/1
PURPOSE: The Southern Route Optical upgrade will allow sites in the
southern region to have
greater flexibility by not having to regen paths for greater distances,
and this in turn saves
costs.
SCOPE: Migrate Coachella from a CWDM network to a DWDM network
IMPACT: Coachella sites will be impacted during the maintenance window,
but campuses with Redundancy should only have one path taken down at a time.

6/27 – Riverside PoP to PDC (Riverside services facing San Diego will be
impacted)
