Could my Internet Service Provider be limiting my bandwidth to non-speed test websites, and how can I verify this?

Is Your Internet Service Provider Throttling Your Bandwidth? Here’s How to Investigate

Many internet users have experienced fluctuations in their internet speeds, leading to concerns about whether their Internet Service Provider (ISP) is intentionally throttling bandwidth to certain websites. If you suspect that your ISP may be limiting your speeds, especially to sites other than speed test platforms, you’re not alone. Here’s how to investigate and potentially prove your suspicions.

The Problem at Hand

I’ve personally noticed that my internet speed fluctuates significantly, often ranging between 200KB/s and 1MB/s, while sitting around a consistent 400-500KB/s for most of my usage. A peculiar observation is that whenever I access a speed test site, my connection remains stable and reaches the promised 10 Mbps that I pay for—something that doesn’t happen with other types of traffic.

Interestingly, during a past interaction with tech support for a different issue, I was asked to run a speed test. Just as I informed them I was ready, the download I had running in the background unexpectedly surged to approximately 18 Mbps and remained there until I finished the test. This raised immediate red flags regarding my ISP’s practices.

Investigating Bandwidth Throttling

If you find yourself facing similar inconsistencies, here are some steps you can take to investigate further:

1. Conduct Regular Speed Tests: Use various speed test sites to monitor your connection at different times of the day. Look for patterns in speed consistency, especially when comparing speed tests with your regular internet usage.

2. Run Tests During High Usage: Try conducting speed tests while simultaneously using various services, such as streaming or downloading large files. Pay attention to any discrepancies in performance during these simultaneous activities.

3. Monitor Background Usage: Ensure that no other devices or applications are using your bandwidth while you run these tests. This will eliminate variables that could skew your results.

4. Upgrade and Track: If you decide to upgrade your internet plan for higher speeds, monitor if the same bandwidth fluctuation patterns persist. Notably, if your speeds still appear to be throttled to levels consistent with your old plan, this may support claims of throttling.

5. Document Everything: Keep detailed records of your findings, including speed test results, times of day, and specific circumstances. This information could be invaluable if you decide to present your case to your ISP or a regulatory body.
