Concord Broadband has enlisted the services of the manufacturer of all hardware at all customer locations and networking equipment that provides a path to the internet to perform software upgrades to the latest stable releases. The vendor has told us to expect two brief outages for each customer: one (around 1 minute) for the ONT upgrades for devices in customers’ homes, and one longer one (under 20 minutes) for the card on each device at our operation centers that provides internet service.

The work will commence at around 1am on Friday, February 23, and we expect all work to be complete by 6am. Individual cards will be rebooted sequentially to lessen the impact on all customers. Each user's total impact time should be under 15 minutes.

Should you find yourself offline after the end of the maintenance window, please contact our 24x7 Helpdesk at (978) 318-3199 or send an email to broadband@concordma.gov.

Performing upgrades like this ensures network security and stability and is a standard practice across the industry. We thank customers for their understanding!
