Because of COVID-19 (the coronavirus), more small-business owners are working from home than ever before. In response to the outbreak, internet providers are offering to help out.

All internet companies nationwide are pledging to waive any late fees or data overages for the next 60 days. In addition, certain companies are offering special deals and upgrades to new and existing customers.

Comcast Xfinity’s Internet Essentials program offers two free months of service to new customers and unlimited data use for 60 days to all subscribers. Additionally, the provider is allowing anybody to use Xfinity hotspots for free and is automatically increasing internet speeds for all essentials customers.

Cox is offering the first month of its low-income internet program, Connect 2 Compete, for free until May 12, 2020. The provider is also giving free phone and remote desktop support.

We updated this piece with CenturyLink’s newest plan and pricing info.

Like the Little Engine That Could, CenturyLink has chugged along for decades, expanding its communication and technology services throughout the United States. If you’re looking for small-business internet to keep your company on track, CenturyLink has a few reasonably priced plans.

CenturyLink is best if you need an affordable plan and always-available tech support

We compared CenturyLink DSL internet costs to other business internet service providers. CenturyLink emerged as one of the most affordable.

Although some providers offer a wider range of plan speeds and costs, CenturyLink offers a few solid plans at prices that won’t bludgeon your budget. The most expensive plan—Simple Internet 940—is cheaper than the same speed plan offered by both AT&T and Comcast.

CenturyLink Business Internet plans and pricing

Very small businesses that don’t need a ton of online computing power can get by with the slower plans in the 10 to 40 Mbps range. The monthly prices for these plans aren’t too high, which means they are a reasonable option if you’re looking for basic internet.

CenturyLink also gives you free tech features with most business plans, including two licenses for Microsoft Office 365 Business Essentials and 20GB of data backup. These perks are great for new businesses that need some basic technology to improve their operations.

If you need more speed—say, for downloading large files or streaming video—you should consider CenturyLink’s upper-tier plans.

Unfortunately, we couldn’t track down down upload speeds for any of CenturyLink’s Business Internet plans. Upload speeds matter if you need to do a lot of file uploading or conduct videoconference calls because slow uploads can lead to interruptions for these services.

Our recommendation: before you sign up for any CenturyLink Business Internet plan, ask about the plan’s max upload speed.

Anything below 1 Mbps is too low for most businesses. But unless you expect your operations to demand a lot of uploading power, you can likely get by with upload speeds in the 1 to 10 Mbps range.

Fiber internet plans

Like most other major internet service providers, CenturyLink has been building a fiber-optic network to deliver speeds faster than any DSL connection. For now, some details about CenturyLink’s fiber service—like pricing and specific availability—are murky.

Click the links in the table below to check if fiber is available in your area and to ask CenturyLink for a quote. But for now, here’s what we do know, starting with a list of plans.

Fiber is famous for its capability to provide true gigabit internet—that’s a thousand megabits. Speeds this blazingly fast are great for uninterrupted, complicated online work.

CenturyLink fiber plans also boast symmetric speeds, which means their upload speeds match their download speeds. This is a godsend for businesses that need to connect many users, upload large files, and run demanding online point-of-sale systems—all with minimal lag.

Technology and extras

CenturyLink entices business customers with a few perks that can make running your company a bit easier. These extra technologies are included with many CenturyLink plans and bundles:

  • Up to 10 licenses for Microsoft Office 365 Business Essentials: Go beyond the personal Microsoft Office suite and get access to tools like email, calendars, file sharing and backups, online conferences, team sites, and more—all synced to the cloud so you can work from anywhere.
  • Website services: Register your business’s domain name with up to 5GB of data, search engine listing, and online faxing.
  • Online backups: Securely back up 10GB of your precious business data to the cloud for up to 20 devices.
Watch out

Static IPs are a must for businesses that host their own servers or use remote access for employees and vendors. This is a feature CenturyLink lacks, so be careful if you use services that rely on an unchanging IP address.

Reliability and support

Modern businesses rely on internet for many day-to-day functions, from communication and collaboration to point-of-sale transactions and customer service. Here’s how internet from CenturyLink stacks up to competition for reliability and support in case of trouble.

CenturyLink uptime reliability

You’d like your internet to work 100% of the time, wouldn’t you? Unfortunately, no service provider can realistically guarantee perfection. CenturyLink agrees to 99.9% uptime* for its business internet plans, which according to our research is the industry standard.

This 99.9% uptime translates to about 43.8 minutes of downtime in a one-month period. That shouldn’t worry too many customers. On the other hand, if your business would be seriously impacted by an internet outage, you may want to find a company like Verizon that offers a higher guarantee.

Based on conversations we had with several providers’ customer service representatives, these are the current uptime guarantees in the market:

GuaranteeDowntime per monthDowntime per year
99.9% (CenturyLink DSL; AT&T Fiber*)43.8 minutes8.76 hours
99.95% (Verizon DSL*)21.9 minutes4.38 hours
99.99% (Verizon Fiber*)4.38 minutes52.56 minutes
99.998% (Comcast*)52.56 seconds10.51 minutes

*Uptime guarantees confirmed from online chat conversations with internet service provider representatives.

CenturyLink business support

Here’s one bright area of this review: technical support. CenturyLink offers 24/7 technical support for business internet plans and packages—a vital lifeline in case you experience a serious outage or problem.

What’s more, you can purchase remote IT support starting at $19.99 per device per month to get even faster and more detailed service.

CenturyLink internet reviews and ratings

How do industry leaders and customers rate CenturyLink service? The answer is somewhere between below average and so-so. Let’s look at a couple different factors.

  • American Customer Satisfaction Index (ASCI): In 2019, ACSI rated customer satisfaction with CenturyLink at 59/100—up one point from the previous year and higher than Frontier Communications.1
  • Better Business Bureau (BBB): The BBB, which uses customer complaints to form its ratings, currently lists CenturyLink as “Not Rated”—which means the company is in the process of resolving ongoing complaints while undergoing government action.2

These results are a bit disheartening. But if CenturyLink can better respond to customer complaints, there’s definitely room to improve the company’s reputation.

The fine print

Let’s get down to details: here are some of the fees you might have to pay, contracts you might have to sign, and hardware you might have to buy to get CenturyLink business internet.


No one likes hidden fees, but CenturyLink is up front about the extra fees you have to pay to sign up or make changes to your service.

  • Activation fees: You pay $99 to activate a new business internet connection.
  • Installation fees: The standard fee is $59.99 for CenturyLink to install your services. No word on whether you can avoid the fee by installing the equipment yourself.
  • Early termination fees: The standard fee is $400 prorated by the amount of time remaining on the contract.


The DSL plans we could find all require a two-year contract to get the prices we show. You also must agree to automatic payments and electronic billing to get those prices. Fiber plans require a one-year contract.


To get up and running, you’ll need to purchase or rent a modem from CenturyLink. You can own the modem outright for $100, or you can lease it monthly for $10.

FAQs about CenturyLink business internet

We discovered a few frequently asked questions about CenturyLink from current and prospective customers. You’ll find our research-backed answers to some of these questions below.

Why did CenturyLink acquire Qwest and Level 3?

CenturyLink has gone through several changes over the last few years, including expanding its footprint and market share through acquisitions.

You can own the modem outright for $99.99, or you can lease it monthly for $9.99.

In 2011, CenturyLink acquired the larger Qwest Communications for $12.2 billion.3 At the time, both companies were focused on phone services, but the merger likely helped the newly formed corporation expand its internet capabilities.

More recently, CenturyLink merged with Level 3 Communications, combining their technology prowesses to serve even more customers and businesses throughout the globe.4

What’s the difference between DSL and fiber internet?

Internet technology has grown leaps and bounds since the days of dial-up connections. Today, high-speed internet comes in a few forms, mainly digital subscriber line (DSL) and fiber-optic.

Business Internet 10
Just need the basics? Connect one or two employees to run email, messaging, and point-of-sale systems—starting at $54.99 per month.

DSL internet uses existing copper wire phone lines to provide internet to business and residential customers. Download speeds using DSL connections range from a few megabits per second to, in rare cases, a couple hundred Mbps.

Although it uses ordinary phone lines, the internet connection via DSL doesn’t interrupt the phone services like traditional dial-up connections. A downside to DSL is that speeds and reliability can be affected by the physical distance between connections. In addition, DSL upload speeds rarely come close to download speeds, leaving some modern technology services at risk for gaps and lags.

Fiber-optic internet, or simply fiber, uses some of the best technology available to deliver internet speeds many times faster than the average DSL speeds.

Fiber connections offer fewer interruptions and more bandwidth for uploads. But fiber internet hasn’t expanded to cover as many customers as DSL (yet) and prices can be much steeper.

The takeaway

CenturyLink business internet plans are an affordable choice for small businesses that need low to average speeds.
