Code Upgrade Planned Network Maintenance

Dear Cogent Customer,

As a valued customer, Cogent is committed to keeping you informed about any changes in the status of your service with us. This email is to alert you regarding maintenance we will be performing on our network:

Start time: 12:00 AM (local time) 11/13/2018
End time: 06:00 AM (local time) 11/13/2018
Expected Outage/Downtime: 45-60 minutes

Cogent customers receiving service in the greater Vancouver, BC 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 Vancouver, BC metro area may experience high latency, re-convergence and/or suboptimal routing which may vary during this window.

We encourage all our customers to please check our network status page http://status.cogentco.com/ which includes any code upgrades that are occurring in the next 48hrs.

Our network operations engineers closely monitor the work and will do everything possible to minimize any inconvenience to you.

We appreciate your patience during this work.
