Twenty-five years ago today, nearly three thousand people were killed in the attacks of September 11, 2001. We pause, with the rest of the country, to remember them, the people in the towers and the Pentagon and the four planes, the first responders who ran toward the danger, and the families who have carried the loss for a quarter century.
There is nothing to add to that grief. Only to honor it.
We do want to mark one part of that day's legacy, because it is close to the work we do and easy to forget: September 11 changed how a nation reaches its people in a crisis.
The silence of that morning
In the hours after the attacks, one of the quiet catastrophes was communication itself. Cell networks buckled under the surge and jammed. People could not reach the people they loved. Warnings could not travel fast enough to the people who needed them. First responders' radios could not talk to one another inside the buildings. In the most connected country on earth, at the moment it mattered most, the systems for reaching each other failed.
The 9/11 Commission would later name those failures plainly. So would Hurricane Katrina, four years on, when timely warnings again could not reach the people in their path. Two catastrophes, one lesson: the ability to warn and to reach people, quickly and directly, is not a convenience. It is a matter of life.
What was built after
Out of that lesson came a quiet, enduring response. In 2006, Congress passed the Warning, Alert, and Response Network Act, and an executive order established what became the Integrated Public Alert and Warning System. Those efforts produced, by 2012, the Wireless Emergency Alerts most Americans have felt buzz in their pocket, the geo-targeted message that can reach every capable phone in a defined area within seconds, without a network jamming, without anyone having to look anything up.
It is imperfect, and it took too long. But it exists because of what September 11 revealed. The tornado warning, the AMBER alert, the evacuation notice that reaches a phone in time, each is, in part, an answer to the silence of that morning.
Why it stays with us
We build communication tools, and days like this are a reminder of what that work is actually for. Beneath the metrics and the features, the deepest purpose of reaching people has nothing to do with commerce. It is the oldest human need there is: to warn the people in danger, to find the people we love, to not be alone with the worst news. September 11 is the starkest reminder of what it costs when that fails, and of the responsibility that comes with the ability to reach anyone at all.
Today we remember the people lost, and the people who ran toward the danger to reach them. Twenty-five years on, we carry it with us.
In memory of those killed on September 11, 2001.
