ISP Throttling Test: Detect If Your Internet Is Being Throttled
ISP throttling is when your internet provider intentionally slows your connection speed, often targeting specific traffic types like streaming video, gaming, or peer-to-peer transfers. Our throttling test detects unusual speed patterns that suggest deliberate bandwidth limitation.
Launch in Mission ControlWhat It Measures
The throttling test compares download speeds across different traffic patterns and port configurations. Significant differences in performance between traffic types can indicate selective throttling. It also tests speeds at different times to detect time-based throttling.
How It Works
- Runs download tests over multiple connections and port configurations
- Compares performance on standard HTTP (port 80) vs non-standard ports
- Tests speeds across different traffic signatures
- Analyzes results for patterns consistent with selective throttling
Why It Matters
ISP throttling reduces the service you pay for without your knowledge. After net neutrality rules changed in the US, some ISPs throttle specific services including video streaming and gaming. Knowing if you are throttled helps you make informed decisions about your ISP.
Understanding Your Results
A consistent speed across all test configurations suggests no selective throttling. A significant drop (50% or more) on certain traffic types compared to others may indicate throttling. Compare results with a VPN to test if bypassing ISP traffic inspection changes your speed.

How do I know if my ISP is throttling me?
Signs include consistently slower speeds at peak hours, specific services (like Netflix or YouTube) loading slower than general browsing, and speeds that improve significantly when using a VPN. Our throttling test checks for these patterns automatically.
Is ISP throttling legal?
In the US, throttling is currently legal after net neutrality rules were repealed. ISPs must disclose throttling in their terms of service but are not required to avoid it. In the EU and some other countries, stronger net neutrality protections apply.
Can a VPN stop ISP throttling?
A VPN can bypass selective throttling by encrypting traffic so your ISP cannot see what type of traffic you are sending. However, it cannot bypass speed caps tied to your overall plan tier. VPNs also add some overhead latency.
Why is my internet slow at peak hours?
Slowdowns during peak evening hours are usually network congestion rather than deliberate throttling. Congestion happens when many users share the same infrastructure simultaneously. Deliberate throttling tends to be more consistent and targeted at specific services.
