Just after the Columbine massacre companies jumped on board to deliver SMS alerts to their staff and students. When I saw what they were charging and how delayed their service was (sending only 30 messages a second or so) it meant that by the time the message got to the student, the active shooter was long gone. Now an organization that’s big enough to support thousands of messages a second is doing something that all of us emergency managers have longed for – team up with emergency agencies and special districts to push out SMS messages for free. That organization is Twitter. You can read more about their new program and sign up for alerts by clicking here.
