The data center had scheduled maintenance for the core network to complete hardware upgrades which needed to ensure long term reliability.

DATE: Sunday, October 31st, 2021
END TIME: 4:00 AM CDT (UTC -5)
MAINTENANCE SCOPE: Chicago core routers located at 350 E Cermak Rd.


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, the upgrade will be suspended 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.

If you have any questions about this planned work, please email [email protected]
