Company: Service issues cut the ability to deliver

This message is regarding the broadcast sent by the district on Jan. 24.

SchoolMessenger, like all mass notification services, must rely on independent phone carriers for “last mile” delivery of messages. A service disruption with an independent phone carrier in a local area can cause users of a mass notification service to experience intermittent periods in which the delivery of phone calls cannot occur.

While the SchoolMessenger service makes multiple attempts over a period of time, continued inability to properly route calls through a local carrier eventually results in no delivery.

On the morning of Jan. 24 when SchoolMessenger handed off calls to numbers owned by Verizon Maryland, a last-mile provider in Allegany County, a significantly higher than expected number of these calls could not be delivered.

Over 99 percent of the phone numbers experiencing a delivery issue during this broadcast have been traced to Verizon Maryland, with the largest concentration in the 301-777-XXXX exchange.

Given this, the early findings are that a service issue with Verizon Maryland limited the company’s ability to deliver to numbers maintained by Verizon Maryland.

The issue with Verizon Maryland appears to have been remedied as broadcasts have since continued without interruption.

Thank you for your time on this matter. We take seriously our commitment to delivery and will continue to employ systems and practices to ensure the highest possible rates of deliverability.

Please feel free to contact me if I can be of service.

Nate Brogan, vice president

SchoolMessenger

Los Gatos, Calif.
