Scheduled tor1 network maintenance - 09-Mar-2022

Post by porcupine »

Hi Folks,

Please be advised of the following maintenance window:

Maintenance Window: Wednesday March 9th, 2022 - 11:00pm - 2:00am Eastern time
Facility: Tor1, Tor2
Affected Device(s): dwdm1.tor1, core01.tor1
Affected Customers: Tor1 general network, East path wave services
Service Impacting: Yes - The work in question will have the potential to cause several small outages/connectivity drops.

Details: We will be physically relocating the DWDM unit which provides wavelength services for the east fiber path connecting our Tor1/Tor2 facilities.

While connectivity between the facilities operates over a redundant pair of DWDM units (covering the East and West fiber paths), customers may notice a very brief hiccup when one fiber path is dropped.

We expect the physical migration to take ~10-15 minutes, during which time the connectivity between the facilities will not be redundant, and will be operating off only the West path. Customers directly connected to the dwdm1.tor1 device will see their wavelength services go down for ~10-15 minutes during this window, while we do not anticipate any appreciable impact to other customers, due to the redundancies in place.

During this maintenance, several configuration changes and optimizations will also be made to the configurations/setup on the core01.tor1 router. While we are hoping these do not interrupt traffic at all, we are doing the changes during a posted maintenance window, just in case there are any unexpected surprises/etc.

As always, we will be carefully performing the maintenance work in question, and will use every reasonable measure to attempt to mitigate any unnecessary outages/incidents/etc.
