Start time: 12:00 AM (local time) 01/13/2017
End time: 06:00 AM (local time) 01/13/2017
Cogent customers receiving service in the greater Birmingham, AL, Southfield, MI and Memphis, TN metro area will be affected by this maintenance. Only the Cogent Order ID(s) listed above will be impacted. The purpose of this work is to apply and activate software module upgrades on code running on the edge routers per the manufacturer's recommendations.
During this maintenance window, you may experience up to two brief interruptions in service while we complete the maintenance activities. However, due to the complexity of the work, your downtime may be longer. Customers may also see some re-convergence during the maintenance window. Customers may experience latency and packet loss intermittently throughout the window.
Over the days following this initial upgrade, we will be upgrading code on redundant upstream routers. Cogent customers receiving service in or transiting the greater Birmingham, AL, Southfield, MI and Memphis, TN metro area may experience high latency, re-convergence and/or suboptimal routing which may vary during this window.
