General Questions

Q: What is UCB WarnMe? When will it be used?

UCB WarnMe is the notification system serving the UC Berkeley community. Emergency notifications are sent via the Everbridge platform (previously called Nixle) upon confirmation of a significant emergency or dangerous situation occurring on the campus that involves an immediate threat to the health or safety of students or employees. UCB WarnMe is also used to send timely warnings and community advisories from the campus police (UCPD)

UCB WarnMe is just one part of our alert and warning system that may be used on campus. In case of an actual emergency, the university may also utilize the alert and warning siren system, the university email system, social media, or verbal announcements via public address systems. The university may also post updates during a critical incident on the university homepage. If the situation warrants, the university will establish a telephone call-in center to communicate with the campus community during an emergency situation.

UCB WarnMe notifications are sent via the Everbridge platform (previously called Nixle) to ensure reliable service 24/7. Everbridge specializes in rapid public notification and has redundant infrastructure. Notifications sent via email will have an Everbridge image header.

Some examples of incidents that may prompt an emergency notification include a(n):

*Please note that this list is not exhaustive.

Timely warnings and informational community advisory messages are also sent via UCB WarnMe.

Messages will be sent in written text (text messages and/or email). UCB WarnMe emails are sent from “noreply@everbridge.net” and display “UC Berkeley Police Department” as the sender.

The UCB WarnMe system will make its best attempt to deliver messages, but situations and services outside the campus's control mean that we cannot guarantee delivery of all messages to all devices. For example, if the local cell phone network is overloaded, you may not receive SMS alerts on your mobile device.
