Core Network Maintenance (Chicago)
Posted by Kevin Stange on 25 October 2021 11:12 AM
We have scheduled maintenance for our core network to complete hardware upgrades needed to ensure long term reliability.
Date: Sunday, October 31st, 2021
We will be completing hardware upgrades to the core routers servicing our Chicago network at 350 E Cermak Rd (chi01, chi02) and 725 S Wells St (chi18). This work is designed to be completed without disrupting network services using a vendor-recommended procedure. To minimize the risk of customer impact, only one router will be worked on a time, and time will be allowed between upgrades to ensure the first router is stable before performing the steps on the second router.
If router disruption should occur, brief periods of inaccessibility or suboptimal routing may occur during the maintenance. If this occurs, we will suspend work and restore the operations for the affected router before continuing further maintenance. If this does not leave time to upgrade both routers, the second router will be deferred to a future maintenance.
