Update: 911 service restored

Friday, Sept. 15, 5:30 p.m. — Emergency dispatch centers in Palo Alto and Mountain View are receiving 911 calls again. But while the service has been restored, the cause of the outage hasn’t been determined. The calls use AT&T lines, and Mountain View described the outage as “widespread.” AT&T has not returned the Daily Post’s emails seeking more information.

Friday, Sept. 15, 3:34 p.m. — Palo Alto and Mountain View police say the connection between 911 and their dispatchers has failed this afternoon.

Palo Alto police say that if a person needs emergency assistance (police, fire or medical), call 911 and the call will be routed automatically to Santa Clara County Communications.

Police said they’ll advise when regular service has been restored.

Mountain View has put out the same message. Mountain View called it a “widespread outage” by AT&T.

Mountain View says its non-emergency line — (650) 903-6344 — is still operating.
