Throttling

The intentional slowing of internet service by an ISP, either for specific activities (like streaming or torrenting) or after exceeding a data threshold on an "unlimited" plan.

What It Means

ISPs may throttle specific traffic types (video streaming, peer-to-peer), specific services (Netflix, YouTube), or all traffic after a data threshold. Throttling is often invisible to users — Netflix may load at 480p instead of 4K without any error message. A VPN can sometimes bypass activity-based throttling because it encrypts traffic so the ISP cannot identify what you are doing. If your speed test shows fast speeds but streaming is slow, ISP throttling may be the cause.
