Major Network Outage Lessons for Business: Why One Internet Connection Is Not a Continuity Plan
A September 2026 FAA equipment outage caused major ground stops across Northeast airports. The event is a useful reminder for businesses: primary internet, backup connectivity, power and tested failover are separate parts of continuity planning.
What the September 21 outage showed
FAA Air Traffic Control System Command Center advisories on September 21, 2026 documented equipment-related ground stops affecting major Northeast airports. The operational disruption illustrates how dependent modern organizations are on communications infrastructure.
A small business has a very different network from the national air-traffic system, but the resilience principle is transferable: when one connection carries every payment, phone, cloud and customer workflow, a single failure can stop much more than web browsing.
Start by identifying what absolutely must stay online
List the systems that stop revenue or operations when connectivity fails: point-of-sale, VoIP, scheduling, cloud applications, authentication, remote access, cameras, online ordering or customer service. Rank them by urgency.
The backup connection does not always need to match the primary speed. A restaurant may need enough capacity to preserve payments and online orders, while a medical or professional office may need broader cloud and voice continuity.
A second connection should reduce shared failure risk
A backup is more valuable when it uses a meaningfully different access path from the primary service. Wireless or satellite can sometimes provide path diversity from local wired infrastructure, while a second wired provider may offer other advantages when the routes are sufficiently independent.
Do not advertise complete independence unless it is verified. Two services can still share building power, conduits, poles, upstream facilities or other points of failure.
Test power, routing and the applications—not just the backup modem
Failover planning should include the router or firewall, switches, access points, phones, payment terminals and any equipment that must stay powered. A live backup modem is not enough if the network hardware or critical endpoints are offline.
Run planned failover tests. Confirm that applications reconnect, DNS works, VPNs or authentication still function, and employees know which nonessential services should be limited during backup operation.
