What Happens When Your Business Internet Goes Down and What You Can Do About It

A practical preparedness guide from someone who has seen it happen hundreds of times

By Natthawut (Ton) Khamnuadi • June 2026 • Business Account Executive at Metronet, Wichita Falls, TX

Nobody thinks about their internet until it stops working. I know this because I have spent over a decade in telecom, and the most panicked phone calls I have ever received all start the same way: "Our internet is down and we do not know what to do."

When I was managing a Spectrum store on Kemp Blvd here in Wichita Falls, I took those calls daily. Business owners who were losing money by the minute, with customers standing at the counter and employees sitting around unable to work. The ones who had a plan got through it. The ones who did not lost real money and real customers.

This article is meant to do two things. First, I want to walk you through exactly what happens when your business internet goes down so you understand the full scope. Second, I want to give you a step-by-step plan so that if it happens to you, you already know what to do.

The Cascade: What Actually Happens in the First 60 Seconds

Most business owners think an internet outage just means they cannot check email for a while. That is not how it works anymore. In 2026, almost everything in a business runs through an internet connection, and when it drops, things fall apart fast.

Your POS system stops processing payments

If you run a retail store, restaurant, salon, or any business where customers pay with cards, this is the first thing you feel. Most modern POS systems are cloud-based. Square, Clover, Toast, Lightspeed. They all need an active internet connection to authorize transactions. Some have an offline mode that queues transactions, but many business owners do not know it exists or have not enabled it. Without it, you are cash-only the moment your connection drops.

Here is the math on that. According to a 2024 Forbes Advisor survey, 84% of consumers prefer to pay with a debit or credit card over cash. If you cannot accept cards, you are turning away roughly 8 out of 10 customers who walk through your door.

Your phones go silent

If your business uses VoIP phones (and most businesses do now, whether they realize it or not), those phones are dead without internet. No incoming calls, no outgoing calls. If a customer calls your business and gets nothing, they are calling your competitor within 30 seconds. Vonage, RingCentral, 8x8, Nextiva, Microsoft Teams calling. All of them require an internet connection to function.

Cloud software becomes inaccessible

QuickBooks Online, Google Workspace, Microsoft 365, Salesforce, your scheduling software, your inventory system. If it runs in a browser or syncs to the cloud, it is gone. Your employees cannot pull up customer records, cannot access files, cannot send invoices. For businesses that have moved everything to the cloud (which is most businesses at this point), losing internet is the same as losing access to every tool you use.

Security cameras and alarm systems can go offline

Many modern security systems are IP-based and rely on your internet connection to send alerts, store footage in the cloud, and allow remote viewing. When the internet goes down, your cameras may still record locally, but you lose remote monitoring and real-time alerts. For businesses that rely on monitored alarm systems through an IP connection, this creates a security gap during the outage.

Employees sit idle

This is the part that adds up the fastest. If you have 10 employees and each one makes $18 an hour, that is $180 per hour in wages for people who cannot do their jobs. A two-hour outage costs you $360 in wages alone, not counting the revenue those employees would have generated. For a medical office, law firm, or any professional services business where billable hours are the product, the cost multiplies quickly.

What Downtime Actually Costs

I am going to give you some real numbers here because I think most people underestimate this.

Gartner and other industry research firms have put the average cost of IT downtime at around $5,600 per minute for mid-size and large companies. That number is too high for most small businesses, but the principle holds. The Information Technology Intelligence Consulting (ITIC) group surveyed businesses of all sizes and found that the average small business loses roughly $427 per minute of internet downtime when you factor in lost revenue, idle wages, recovery costs, and customer impact.

Let me put that in local terms. Say you own a restaurant in Wichita Falls doing $800,000 a year in revenue. That works out to about $2,191 per day, or roughly $274 per hour during an 8-hour business day. If your internet goes down for 90 minutes during the lunch rush and you cannot process card payments, you are not just losing $411 in revenue. You are losing the tips your servers would have made. You are losing the customers who walk out and go somewhere else. And some of those customers are not coming back.

For a medical office, the stakes are different but just as high. If your EHR system is down and you cannot access patient records, you may have to cancel or delay appointments. A busy clinic seeing 4 patients per hour at an average reimbursement of $150 per visit is losing $600 per hour of downtime in direct revenue, plus the cost of rescheduling and patient frustration.

The National Federation of Independent Business (NFIB) found that 37% of small businesses have experienced an internet outage lasting more than one hour in the past year. This is not a hypothetical. It is something that happens regularly.

What to Do Right Now (Before an Outage Happens)

The best time to prepare for a business internet outage is right now, while everything is still working. Here is what I recommend to every business I work with.

1. Save your provider's business support number in your phone

This sounds obvious, but I cannot tell you how many business owners do not know their provider's support number when they need it. They end up Googling it on their phone while their business is losing money. Write it down, save it in your contacts, and tape it to the wall next to your router. If you have a business account, make sure you are calling the business support line, not the residential one. Business support typically has shorter hold times and technicians who understand business-grade equipment.

2. Know your account number and service address

When you call in during an outage, the first thing they will ask for is your account number. Having it ready saves 5-10 minutes on the phone. Keep a printed sheet near your router or modem with your account number, your service address (as it appears on the bill), and the make/model of your router and modem. This information speeds up troubleshooting significantly.

3. Learn how to power cycle your equipment

About 30-40% of the trouble calls I handled when I was doing Tier 3 network support at T-Mobile were resolved by a proper power cycle. Unplug your modem and router from power. Wait a full 30 seconds (not 5 seconds, a full 30). Plug the modem back in first and let it fully boot up, which usually takes 2-3 minutes. Then plug the router back in. If your internet comes back, great. If not, now you know the problem is not your equipment and you can tell the provider that when you call.

4. Set up your POS for offline mode

Most modern POS systems have an offline mode that will queue credit card transactions and process them once the connection comes back. Square, for example, lets you accept payments offline and will process them once you are back online. Clover has an offline payments mode you can enable in settings. Toast has offline mode built in. Check your POS provider's documentation and make sure this feature is turned on before you need it. Test it once so you know it works.

5. Have a mobile hotspot ready

A smartphone hotspot is not a permanent solution, but it can keep your most critical system running during an outage. A modern smartphone on a 5G network can deliver 50-200 Mbps, which is more than enough to run a POS system or make VoIP calls. Keep a charging cable near your register or front desk. Know how to turn on the hotspot on your phone (it is in Settings > Personal Hotspot on iPhone, or Settings > Connections > Mobile Hotspot on Android). Some cellular plans restrict hotspot data, so check your plan and make sure hotspot is included.

For Businesses That Truly Cannot Go Down

If you run a medical office, a financial services business, a call center, or any operation where even 10 minutes of downtime creates a serious problem, you need more than a hotspot and a plan. You need a real backup connection and an SLA.

Cellular failover devices

A cellular failover device sits between your modem and your router. During normal operation, it does nothing. When your primary internet connection drops, it automatically switches your network over to a 4G LTE or 5G cellular connection. The switchover typically happens in 10-30 seconds, which means your POS keeps running, your phones stay up, and your cloud applications stay connected.

Devices like the Cradlepoint IBR600C or the Peplink Balance 20X are popular options for small businesses. They cost between $200 and $600 for the hardware, plus a monthly cellular data plan that usually runs $30 to $75 depending on the carrier and how much data you need. For a business that loses $400+ per minute of downtime, this pays for itself the first time your internet goes down.

Dual-WAN with a second provider

For businesses that need the highest level of reliability, the best setup is two internet connections from two different providers on two different types of infrastructure. For example, a fiber connection as your primary and a cable or fixed wireless connection as your backup. A dual-WAN router manages both connections and automatically fails over to the backup if the primary drops.

The key here is that the two connections need to be on different infrastructure. If both your primary and backup connections run on the same fiber line or the same cable plant, a single cut or equipment failure takes both of them down. When I was doing network support for T-Mobile, I saw this happen with businesses that had two internet accounts from the same provider. The provider had one point of failure, and when it failed, both connections went down together.

SLA agreements: what they are and when you need one

SLA stands for Service Level Agreement. It is a written guarantee from your internet provider that includes specific commitments for uptime, response time, and repair time. A typical business SLA might guarantee 99.9% uptime, which translates to no more than 8.76 hours of downtime per year. A 99.99% SLA allows for only 52 minutes of downtime per year.

More importantly, an SLA typically guarantees a response time. A standard business SLA might promise a technician on-site within 4 hours. A premium SLA might promise 2 hours. Without an SLA, you are in the general queue with everyone else, and during a widespread outage, that queue can be long.

SLAs usually come with a higher monthly cost, but they also come with credits if the provider fails to meet the guarantee. For medical offices, financial institutions, and businesses where compliance is a factor (HIPAA, PCI-DSS, SOX), an SLA is not optional. It is part of meeting your regulatory obligations.

SD-WAN for multi-location businesses

If you operate more than one location, SD-WAN (Software-Defined Wide Area Network) gives you centralized management of all your connections across every site. It can automatically route traffic through the best available connection, balance loads between providers, and prioritize critical applications like VoIP and POS over less important traffic like software updates and streaming. SD-WAN solutions from companies like Fortinet, Cisco Meraki, and VMware typically run $50 to $200 per month per location, and they give you visibility into every connection across your business from one dashboard.

Create a One-Page Outage Plan

I recommend every business create a simple one-page document that answers these questions and keep it printed near the front desk or the router. Do not put it on a shared drive that requires internet to access. Print it out.

Your outage plan should include:

  • Your internet provider's business support phone number
  • Your account number and service address
  • Step-by-step instructions for power cycling the modem and router (including the wait times)
  • How to enable the mobile hotspot on the office phone or manager's phone
  • How to switch the POS to offline mode
  • Where the cash register or cash box is located
  • The Wi-Fi network name and password for the backup connection (if applicable)
  • Who to call internally (owner, manager, IT person) if the outage lasts longer than 30 minutes

The person at the front desk at 2pm on a Tuesday should be able to pick up this sheet and follow it without calling anyone. That is the standard. If your plan requires the owner to be present, it is not a real plan.

A Few Things That Are Not Worth Doing

I want to be honest about a few things that I see businesses try that do not actually help.

Having two connections from the same provider is not real redundancy

If both your primary and backup connections run through the same provider's infrastructure, you do not have a backup. You have two accounts that will both go down at the same time. Real redundancy means different providers on different physical infrastructure.

Consumer-grade equipment in a business is a risk

I have walked into businesses running a $60 home router from Walmart handling 20 devices, a POS system, and a VoIP phone system. Consumer routers are designed for a family of four streaming Netflix. They are not built to handle the constant, simultaneous connections a business generates. A business-grade router from Ubiquiti, Cisco, or Fortinet costs $150 to $400 and is built for the job. It is one of the cheapest upgrades you can make that actually prevents outages.

Waiting for the outage to figure out your plan is the most expensive option

Every minute you spend figuring out what to do during an outage is a minute your business is losing money. When I ran my own sole proprietorship hauling oversize loads across all 50 states, I learned fast that you plan for breakdowns before they happen. You know what tow company to call, what shop can handle your equipment, what your insurance covers. It is the same with internet. The planning takes 30 minutes. The outage without a plan can cost you thousands.

Quick Reference: Outage Response Checklist

When the internet goes down, do these things in this order:

  1. Check if it is just your business or a wider outage. Ask a neighboring business, or check your provider's outage map on your phone using cellular data. Downdetector.com is also useful for this.
  2. Power cycle your modem and router. Unplug both. Wait 30 seconds. Plug in the modem first. Wait 2-3 minutes. Plug in the router. Wait 2 minutes.
  3. If it is not back, turn on your mobile hotspot and connect your POS system or most critical device to it.
  4. Switch your POS to offline mode if it did not do so automatically.
  5. Call your provider's business support number. Have your account number ready. Ask if there is a known outage in your area and what the estimated time to repair is.
  6. If the estimated repair time is over one hour, notify your team and begin manual operations (cash transactions, cell phones for calls, paper records if needed).
  7. Document the outage. Write down the start time, end time, and what was affected. You may need this for SLA credits, insurance claims, or to make a case for a backup connection.

The Bottom Line

Internet outages happen to every business eventually. The question is not whether yours will go down. It is whether you will be ready when it does. The businesses I work with that have a plan, a backup connection, and the right equipment barely notice when there is a hiccup. The ones that do not have those things call me in a panic and lose real money while they figure it out.

Thirty minutes of planning today can save you hours of chaos and thousands of dollars later. That is not a sales pitch. That is just how it works.

Want to Make Sure Your Business Is Prepared?

I sit down with business owners here in Wichita Falls and review their current internet setup, their equipment, and their backup plan. It takes about 15 minutes, it is free, and you will walk away knowing exactly where you stand and what to do if your connection drops. If I can help improve your setup, I will tell you how. If what you have is already solid, I will tell you that too.

Let me help you make sure you have a plan before it happens.
