What is ISP Throttling?

ISP throttling is when an internet service provider intentionally slows a user’s internet connection for certain types of traffic or during specific periods of time. Rather than cutting off access entirely, the provider limits available bandwidth, which can make activities like streaming, downloading, or browsing feel noticeably slower.

Throttling is often applied selectively. High-bandwidth activities such as video streaming, online gaming, and file sharing are common targets because they place greater demand on network resources. In some cases, throttling may also occur during peak usage hours, when many users are online at once.

ISPs use throttling for a few key reasons: to manage congestion on shared networks, enforce data limits on certain plans, or prioritize specific types of traffic. The approach can vary depending on the provider and the terms of the user’s service plan.

Using a VPN can sometimes make it more difficult for an ISP to identify the type of traffic being transmitted, which may reduce the likelihood of service-specific throttling. However, a VPN does not increase your underlying internet speed.
