I think my ISP is throttling my bandwidth to sites that aren’t speed test sites, is there any way to prove this?

Is My ISP Throttling My Internet Connection? Here’s How to Prove It

As internet users, most of us have experienced the frustration of fluctuating speeds, especially when streaming, gaming, or working from home. One concern that often arises is whether Internet Service Providers (ISPs) engage in throttling—intentionally reducing the speed of a user’s internet connection. If you suspect that your ISP may be throttling your bandwidth outside of speed tests, you’re not alone, and there are ways to validate your suspicions.

The Speed Test Dilemma

Recently, I noticed a significant inconsistency in my internet speeds. Typically, my download speed hovers between 200KB/s and 1MB/s, averaging around 400-500KB/s. However, whenever I access a speed test website, my connection seems to perform perfectly, consistently registering the 10Mbps that I subscribe to. This contradiction raises the question: is my ISP limiting bandwidth to certain types of traffic while optimizing speed tests?

A striking incident occurred during a previous interaction with Tech Support. When asked to conduct a speed test, I noticed that my background download surged to approximately 18Mbps—the moment I indicated that I was ready to begin. This pattern seems to occur regularly whenever I engage in direct testing, making me wonder if there is a connection between my suspicions and the observed behavior.

Establishing Evidence of Throttling

So, how can one effectively prove that their ISP is throttling bandwidth? Here are a few strategies that can help gather evidence:

Consistent Monitoring: Regularly monitor your internet speeds using various tools and applications. Note the speeds during different times of the day and while engaging in different online activities (streaming, gaming, etc.). This information can serve as a critical baseline for any discussions with your ISP.
Document Activity: Keep a detailed log of your internet usage. Record the time of day, the type of activity, and the corresponding speeds you experience. This documentation can provide tangible evidence during any future communications with the ISP.
Use VPN Services: A Virtual Private Network (VPN) can help disguise your internet traffic, potentially bypassing any throttling measures. By conducting speed tests with and without the VPN, you may notice a difference that supports your claims.
Engage with Community Resources: Reach out to online forums, social media groups, or local networks to see if other users in
