What is throttling, and is it happening to you? If you’re experiencing slower internet speeds than you’re accustomed to, you may be browsing during a peak usage time, using equipment that needs attention or competing with other users in your home for bandwidth. Another common reason for lagging speeds is internet throttling, the act of intentionally slowing internet speeds by your internet service provider (ISP). Figuring out how to stop internet throttling, however, can be a bit tricky.
What is throttling?
What is throttling, and is my internet being throttled? Internet throttling, also known as data throttling and bandwidth throttling, is when your ISP limits your bandwidth or slows your connection to certain online activities after you’ve reached a monthly limit, commonly referred to as a data cap.
This industry practice can be especially annoying for those who utilize their internet connection for gaming, video streaming and file downloads. Once your ISP begins to throttle your connection, you may experience buffering while streaming services like YouTube TV or Netflix, as well as lags or delays in gaming and file transfers. But is my internet being throttled? If you experience these problems, then data throttling might be the source.
Why do ISPs throttle internet and is it illegal?
In most instances, internet throttling is perfectly legal as long as the provider makes the customer aware of it within the fine print details.
“Throttling often is done without users explicitly opting in, and disclosures are often in fine print, so many users may have no idea this is happening and may have no option to turn it off except to pay even more,” said David Choffnes, assistant professor in the College of Computer and Information Science at Northeastern University.
Choffnes and a team from Northeastern University worked with a team from the University of Massachusetts Amherst to investigate throttling of video content by mobile and fixed-line providers using an app they developed, Wehe.
Some internet plans come with data restrictions to limit monthly data usage. When consumers reach this limit before the data cap resets, instead of cutting off the internet connection altogether, providers drastically reduce a household’s internet speeds to prioritize bandwidth to homes that are still within their data limit. One way of preventing this problem is to limit monthly data usage.
You may also be experiencing symptoms of throttling due to high usage in the area during your browsing time. Now that users rely on their connection to work and learn from home, the time previously defined as Internet Rush Hour is hard to pin down. Today’s internet users could experience throttling issues at any time of the day. Internet connection types that involve sharing bandwidth with local users – like cable internet, for example – are especially susceptible to congestion-related throttling. Does Spectrum throttle internet when networks are congested? What about Comcast throttling or Xfinity throttling? In each case, congested networks can lead to data throttling by these ISPs.
Sometimes companies or other entities can pay their ISP for prioritized access and speed. This translates to some people getting internet fast lanes at the expense of others being put in a relatively slow lane. For instance, if a service provider is experiencing congestion in their network, those who have paid prioritization will be the last ones to have their data throttled.
How to tell if your internet is being throttled
Here are a few steps to quickly and easily find out if you’re experiencing bandwidth throttling
Step 1: Run a speed test
Use our speed test to get an initial read on your internet speeds. Be sure to run the test when your internet connection isn’t being used, as online activities like downloading large files can influence your speed test results.
Pro Tip: For best results, use an Ethernet cord to connect your router or modem directly to your device before you run the test.
Step 2: Run a speed test on a Virtual Private Network
After your first speed test, install a Virtual Private Network (VPN) and then run the test again. A VPN-run speed test should help indicate whether your service provider is selectively throttling your internet during certain times of the day or types of internet usage. In some cases, your internet service provider may only throttle speeds during specific online activities such as torrent streaming.
Some internet providers can tell when you’re running a speed test and will pause throttling until the test is over to avoid detection. A service, like Express VPN, can help to mask your internet activities and give you a more accurate speed test no matter what you’re using the internet for.
Step 3: Compare speed test #1 and #2
Take your results from speed test #1 and #2 and compare. If your results are similar, that’s a good indication that your provider is not throttling your internet speeds. If your VPN speed test result is much faster, your provider may be throttling your speeds. Keep in mind that the use of a VPN will decrease your internet speed, but ideally, it shouldn’t have a noticeable impact.
Step 4: Compare your results to advertised speeds
If both of your speed test results match, take a look at that number compared to the speeds you’ve been promised by your ISP. According to FCC reports, most internet subscribers receive speeds that meet or exceed those advertised by their provider. If your speed test results differ significantly from what you’ve been paying for from month to month, it may be time to think about switching ISPs.
Should you be worried about internet throttling?
According to Choffnes, there are three things to keep in mind. One, it is reasonable for consumers to be concerned about data throttling as they expect to use the service they pay for within legal and reasonable limits. Two, when internet throttling occurs, it can negatively impact the quality of digital content like video streaming, games and download speeds. Third, data throttling can interfere with service and business competition. Some services, like YouTube, might be throttled, while others like Vimeo aren’t.
How to stop internet throttling
If you’ve found that your provider is throttling your internet, there’s not much you can do to stop it if you’re committed to staying with your current provider at your current price point. Browsing on a VPN network or upgrading maybe your best solution.
