Is there a way to verify if my ISP is intentionally limiting my bandwidth on non-speed test websites?

Title: Is Your ISP Throttling Your Internet Speed? Here’s How to Investigate

In today’s digital age, a reliable internet connection is more important than ever. However, many users suspect their Internet Service Provider (ISP) may be throttling their bandwidth, leading to frustratingly slow speeds when accessing various websites. If you’ve noticed inconsistent download speeds, particularly outside of speed test sites, you might be experiencing this issue. Here’s a comprehensive guide on how to determine if your ISP is indeed throttling your connection and what steps you can take to gather evidence.

Understanding Bandwidth Throttling

Bandwidth throttling occurs when an ISP intentionally slows down your internet service after detecting certain types of traffic, such as streaming or downloading large files. Some users report experiencing a notable difference between their speeds on regular websites versus dedicated speed test platforms, where they consistently achieve their maximum subscribed speeds.

Your Experience Analyzed

From your description, it sounds like you’re facing significant fluctuations in your download speeds, ranging from 200KB/s to 1MB/s, with an average around 400-500KB/s. Interestingly, when you perform speed tests, you consistently receive the full 10Mbps that you pay for, but only on those specific sites. This raises the suspicion of throttling on other types of internet traffic.

Moreover, previous interactions with tech support revealed curious behavior: during a support call, your download speed inexplicably spiked to 18Mbps just as you were about to conduct a speed test. Such occurrences can make it difficult to assess whether the throttling is indeed an issue or merely a coincidence.

Steps to Prove ISP Throttling

1. Perform Multiple Tests: Conduct speed tests at various times throughout the day and evening. Use different speed test websites to compare results. Note any discrepancies between these results and your general browsing experience.

2. Monitor Background Activity: Utilize tools to monitor your network traffic. This can help you identify if certain applications or services are being throttled compared to others.

3. Check for Traffic Management Notices: Review your ISP’s terms of service for any mention of traffic management policies. Many providers disclose their throttling practices, especially during peak usage times.

4. Test With a VPN: Using a Virtual Private Network can mask your online activities from your ISP. Conduct speed tests and browse normally while connected to a VPN to see if performance improves. An increase in speed while using a VPN may indicate that your ISP is
