It often starts with congestion: a cough, a blockage, or a restriction in a pathway we depend on to function. I am not talking about COVID-19 in the human body. I am talking about the effect the pandemic had on the systems that keep our communities and businesses running.
In many ways, the same idea applied. As demand increased and normal patterns changed, supply chains and network infrastructure became congested. Things we had always assumed would be available suddenly were not.
The early warning signs
In January 2020, the CDC issued a travel alert related to Wuhan, China. At that point, the United States had only a small number of known cases. By the end of January, the U.S. government had begun issuing travel restrictions related to China.
In February, I moved my home internet service from Comcast Business to Xfinity Residential. At the time, it seemed like a practical decision. The service offered more bandwidth at a lower cost, and it worked well for my family.
Then, in early March, as head of IT and the Facilities, I needed to purchase hand sanitizer and disinfecting wipes for the office - to replenish our stock. I searched through Amazon and other suppliers, only to find that delivery dates were more than 30 days away. Soon, sanitizer, wipes, and toilet paper became difficult to find almost everywhere.
These were ordinary items we had always taken for granted. We still had some supplies, but not in the quantities we wanted. For me, that was the first real warning sign that the supply chain was under strain. It was the first time in many years that a common item had simply disappeared from online retailers and local stores.
A sudden shift to working from home
By mid March, an incident at our San Jose office required us to begin working from home before the Bay Area issued its shelter in place order. Soon after, California followed with statewide restrictions.
My children were also sent home from school. Two attended Leland High School, and one attended De Anza College. Beginning March 16, 2020, they joined millions of other students across the Bay Area in trying to learn and connect from home.
At the same time, Silicon Valley and much of the region moved to remote work. We did not immediately realize how much pressure this would place on our network infrastructure.
Millions of people were suddenly working from home, attending online classes, streaming video, and trying to stay connected. Children who could no longer see friends in person turned to Netflix, YouTube, Hulu, gaming, and social media. Adults relied on Zoom, GoToMeeting, Webex, and other platforms to keep their jobs moving.
All of it created a massive and unplanned stress test for the internet.
When home internet became a business problem
My move to residential internet had seemed like a good decision in February. But once nearly every household in the area was relying on home connections throughout the day, the service became slow and unreliable.
I had to rethink the setup quickly.
I brought Xfinity Business back into the house because I could no longer depend on a connection that slowed down during the middle of the workday. The contract was not perfect, but it gave me a dedicated 100 Mbps connection, an LTE backup modem, and battery backup for about $120 per month during the first year. The installation and configuration took about two weeks.
In the meantime, my wife and I relied on mobile hotspots to keep working. Sometimes they worked well. Other times, they did not.
The experience made it clear how dependent we had become on systems that were never designed for everyone to rely on them at once.
The growth and growing pains of video meetings
As people adjusted to working and learning from home, platforms such as Zoom became essential. They gave families, schools, and businesses a way to stay connected when in person meetings were not possible.
But the rapid growth also exposed weaknesses. Zoom had been designed for ease of use, and some meetings lacked basic security settings. This made it easier for disruptive people to enter public meetings, sometimes sharing offensive sounds or graphic images.
The platform improved over time, adding stronger security options and better guidance for meeting hosts. Still, the early days were a reminder that rapid growth can reveal gaps in security, capacity, and planning.
Planning for the next disruption
Things are more stable now. Zoom is more secure, and my home internet is generally reliable, even though outages still happen from time to time.
The larger lesson is that we need to look more closely at the capacity of the systems we depend on. Businesses, service providers, schools, and governments all have a responsibility to consider what happens when demand reaches unexpected levels.
Few people imagined that tens of millions of students would need to learn online at the same time, often through video calls. Few expected entire workforces to depend on home internet connections overnight. Yet that is exactly what happened.
One positive outcome of 2020 was that it forced us to rethink what is acceptable and what we need to build for the future. We may not know exactly when a crisis will end, but we can prepare better for what comes next.
That means protecting our supply chains, strengthening our infrastructure, and planning for capacity before we need it.
