Power problems, not cut cables or cyberattacks, are the leading cause of significant outages according to Uptime Institute’s most recent outage analysis report, with failures in UPS systems, transfer switches, and backup generators dominating the list. That single fact surprises most business owners asking what causes internet outages at a business, because the instinct is to assume the internet service provider is always to blame. In reality, the cause is often sitting inside your own building: a failing power supply, an overloaded circuit, or a piece of network equipment that was never given proper battery backup.

Understanding the real causes matters because the fix is different for each one, and treating every outage as “the internet is down, call the provider” wastes time when the actual problem is on your side of the connection.

Power-Related Failures

Power issues top the list of outage causes for good reason. A router, modem, or switch that loses power goes offline immediately, and a business without battery backup on that equipment experiences an outage the moment the power blinks, even briefly. Uninterruptible power supply units, transfer switches, and backup generators are supposed to prevent this, but when any of those fail, the outage that follows can last far longer than the original power event. This is also where local weather plays a direct role. Oklahoma’s severe weather patterns, from ice storms to spring thunderstorms, are a real and recurring threat to power infrastructure, and the National Weather Service’s storm safety guide covers the kind of post-storm hazards, including downed power lines, that can keep a business offline well after the storm itself has passed.

Physical Line Damage

Physical damage to the actual cables carrying your internet connection is another major cause. Construction crews cutting a buried line, animals chewing through cabling, or general wear on aging infrastructure can all sever a connection with no warning. This kind of outage is usually outside a business’s direct control, but  outage reporting system exists to track at the provider level, requiring telecommunications companies to report significant service disruptions so patterns in infrastructure reliability can be identified and addressed over time.

Human Error

Human error is a bigger factor than most business owners assume, and it shows up in both the outage itself and how long it takes to fix. A misconfigured router setting, an accidental change to network equipment, or an unclear internal process for who handles what during an outage can all turn a small problem into an extended one. Uptime Institute’s research specifically calls out “failures to follow established procedures” as the leading driver of human-error-related outages, alongside unclear processes and installation mistakes, which is a preventable category if a business has documented procedures in place before something goes wrong.

Cyberattacks and Equipment Failure

Cyberattacks, including network flooding and malware infections, can also take a connection offline, though they represent a smaller share of total outages than power and physical causes. Equipment failure rounds out the list: aging routers, switches, or modems that were never replaced on a reasonable lifecycle eventually fail, often without warning.

What a Business Can Actually Do About It

A handful of practical steps meaningfully reduce both the frequency and length of outages a business experiences.

• Install battery backup on critical network equipment, not just servers, since a router or switch without power backup is a single point of failure.
• Document clear internal procedures for who does what during an outage, since unclear processes are a leading cause of human-error-related downtime.
• Keep network equipment on a reasonable replacement schedule rather than running it until it fails.
• Build redundancy into your internet connection where possible, such as a secondary connection through a different provider or path.
• Disaster reporting system coverage area with your provider to understand how they report and respond to major regional outages.

The SBA’s business recovery resources recommend treating connectivity as part of a broader continuity plan rather than an afterthought, since a business’s ability to process payments, communicate with customers, and access cloud systems all depend on that connection staying up.

Why Choose CamTech for Network Reliability

CamTech monitors client networks proactively, which means many outage-causing issues, like a failing power supply or an aging piece of equipment showing early warning signs, get caught and addressed before they cause a full outage rather than after. That proactive approach is a meaningfully different posture than waiting for a client to call in reporting the internet is down.

CamTech’s own infrastructure includes datacenters in both Oregon and Oklahoma, giving the redundancy behind its own networking services an extra layer that a single-location provider cannot match, and the team serves businesses across Oklahoma, Arkansas, Texas, and Missouri with that same regional understanding of what actually causes outages in this part of the country. If your Broken Arrow business has been through more unexplained outages than feels normal, that pattern is usually diagnosable, and it is exactly the kind of problem covered in our breakdown of what to do when network down situations hit during business hours.

Leading Causes of Business Internet Outages

Cause	Typically Within Business Control?	Key Mitigation
Power failure (UPS, generator, transfer switch)	Yes	Battery backup on network equipment
Physical line damage	No	Redundant connection path
Human error / unclear procedures	Yes	Documented internal procedures
Cyberattack (flooding, malware)	Partially	Firewall and proactive monitoring
Aging equipment failure	Yes	Scheduled replacement cycle

Each cause and mitigation listed here matches the explanation above: power and human-error causes are largely within a business’s control to prevent, while physical line damage sits mostly with the provider, and cyberattacks fall somewhere in between depending on the security measures already in place.

Conclusion

Internet outages at a business almost always trace back to one of a few specific causes: power failures, physical line damage, human error, cyberattacks, or aging equipment, and each one has a different, practical fix. For a Broken Arrow or Tulsa business tired of losing hours to unexplained downtime, understanding which of those causes is actually behind the pattern is the first real step toward preventing it.

Common Questions About Business Internet Outages

What is the single most common cause of internet outages?

According to Uptime Institute’s most recent research, power-related failures, including problems with UPS systems, transfer switches, and backup generators, are the leading cause of significant outages, ahead of physical line damage and cyberattacks.

Can bad weather really cause an internet outage?

Yes. Severe weather, including ice storms and high winds, can damage power lines and physical cabling, and Oklahoma’s weather patterns make this a real and recurring risk for local businesses, not just a rare event.

Does my internet service provider report outages to anyone?

Larger telecommunications providers are generally required to report significant service disruptions to the FCC through federal outage reporting systems, which helps track infrastructure reliability trends over time, though this reporting happens at the provider level rather than the individual business level.

How can a business reduce the impact of outages it cannot prevent?

Building redundancy, such as a secondary internet connection through a different provider, and having battery backup on critical equipment reduces how much an outage actually disrupts operations, even when the root cause, like a cut line, is outside the business’s control.

Is human error really a major cause of outages?

Yes, more than most people assume. Failures to follow established procedures, unclear internal processes, and installation mistakes are consistently identified as leading drivers of human-error-related outages in industry research.
