Network management

Between Jan 29 (shortly after COVID-19 appeared in the US) and March 26 there was a 105% spike in people active online at home between 9:00 am and 6:00 pm. So why hasn’t the internet ground to a halt? The answer lies in the lessons of Mother’s Day and freeway traffic jams.

Federal Communications Commission Chairman Ajit Pai spoke April 1 with broadband and telephone service providers and trade association leaders about the state of American communications networks as volume and usage patterns shift during the coronavirus pandemic. The Chairman heard from providers across the country who reported network usage had risen about 20-35% for fixed networks and 10-20% for cellular networks in recent weeks, with increased demand in suburban, exurban, and residential areas and during daytime hours.

Everything from meetings at the office to happy hours with friends are all now occurring in digital space. All of this internet use is putting more pressure on our broadband infrastructure. Just in the past few weeks, data demands have risen in nearly all categories.

With Comcast's network performing so well during the pandemic, why did Comcast's data cap exist in the first place? The answer has always been "money," of course—a Comcast executive once acknowledged in a Twitter reply that imposing data caps is a business decision, not one driven by technical necessity.

As the social distancing efforts push everything from school to socializing into video chat, networks have seen huge surges in traffic — and new anxieties over how digital networks will stand up under the strain. So far, both carriers and the Federal Communications Commission insist that the country’s networks are capable of bearing the strain, particularly given the voluntary throttling instituted by many of the most bandwidth-heavy services.

The many changes caused by the COVID-19 pandemic have given the world’s communications networks an impromptu stress test. Data demand has surged and shifted. “Peak hour” — the busiest period of the day on a network — now hits at different times and extends for longer durations. Signs of stress have shown up in other parts of the world so Americans have begun asking: Do our networks have the capacity to meet this surge in demand? Here’s the bottom line.

As so many Americans work from home, as our schoolchildren and university students shift to online learning, as virtually all of our social interactions occur online, a fundamental question looms: Will the internet break? The answer is probably not a simple yes or no, and it’s probably not the same answer everywhere in the United States.

Binge-watching in high-def isn’t an act of irresponsibility in a moment of crisis. “The internet as a whole is fine,” agrees Doug Suttles, CEO of the bandwidth-measurement firm Ookla. “It can handle a ton.”  Coronavirus-induced traffic during the day still doesn’t exceed the nightly peaks your internet provider should have already designed its systems around.

Home internet and wireless connectivity in the US have largely withstood unprecedented demands as more Americans work and learn remotely. Broadband and wireless service providers say traffic has jumped in residential areas at times of the day when families would typically head to offices and schools. Still, that surge in usage hasn’t yet resulted in widespread outages or unusually long service disruptions, industry executives and analysts say. That is because the biggest increases in usage are happening during normally fallow periods. Broadband consumption during the hours of 9 a.m.
