We have scheduled maintenance to upgrade the software of our core routing devices.
Date: Sunday, September 15th, 2019 Start Time: 1:00 AM CDT (GMT -5) End Time: 4:00 AM CDT (GMT -5)
Maintenance Scope: Chicago Facilities (chi01,chi02,chi18)
Periods of suboptimal routing may occur, but no outage is expected. Only one router will be out of service at any time and sufficient network capacity will remain available throughout the maintenance. After each upgrade, we will verify the router is fully operational before continuing with further steps to minimize the risk of any network disruptions.
