Update 12:07 AM: This maintenance was completed without incident. We have scheduled a power supply replacement in one of our distribution switches at our 350 E Cermak Rd location in Chicago, IL to address a failure. Date: Sunday, March 8th, 2015 The affected switch is part of the Chicago public network for customers located at 350 E Cermak Rd in Chicago (facility codes chi01 and chi02). Customers located at 725 S Wells St. in Chicago, IL and in Edison, NJ will not be affected by this work, except if accessing any services or customers hosted at the affected location. Public cloud, backup, and SAN products are not affected. The internal network is not affected. During the maintenance, we will replace a failing power supply identified by our monitoring system. We expect there to be no interruption to this switch as a result of the replacement, however a simultaneous fault in the redundant power supply could cause the device to reboot. This switch is in a redundant pair and each unit has redundant connectivity to the rest of the network. In case of a problem, we expect brief inaccessibility and sub-optimal routing to occur as traffic immediately fails over to the second switch. Traffic will then return to the normal pattern once the rebooting device returns to operation. While the work itself is expected to be completed quickly, we are reserving extra time in case of problems. This will give us the ability to resolve issues without having to extend the maintenance window. If you need assistance during the maintenance, or if you have any questions about this planned work, please contact us via our helpdesk or by calling (312) 602-2689 or (888) 281-9449. | |
