There are a number of tools that try to detect traffic shaping such as Shaper Probe and BonaFide. Internet speed tests are obviously something ISPs won’t shape, so that number tells us nothing. It can be hard to prove that you’re being shaped. Essentially, low-bandwidth services such as email or web browsing may run at the advertised speed, but as soon as you try downloading software or watch a video, that speed goes down. ISPs are buying bandwidth from providers on tiers above them, so although there may be no hard cap on your connection, throttling may be necessary to protect their profits.Ĭonnection shaping happens for various reasons and some of them are genuinely about quality-of-service during peak network congestion, but it can also be a way to advertise faster speeds than a user gets in reality. This is to prevent heavy bandwidth users (often on cheaper packages) from abusing their connection. For example, there may be a rolling monthly bandwidth amount where you’ll be throttled after exceeding it. Some ISP packages may also implement a “soft cap” written into the fine print of your contract. This is when they may decide to throttle or shape connections to prioritize certain kinds of traffic or to fairly share the available bandwidth among all users until things quiet down. However, peak times such as when everyone is streaming video after dinner can put the network under pressure. When networks are quiet, such as at 3AM, the few users who need lots of bandwidth can get it. This can help account for internet throttling due to network congestion. For the most accurate results, perform the speed test at approximately the same time as the control test. So one of the main jobs an ISP has is making sure that everyone on the network has a good experience. Once you’ve installed the VPN, run another speed test.

Since users may not know that only certain types of traffic are being targeted, this mixup is understandable. Often when people say that their ISP is throttling them, they actually mean that they are being shaped. In 2020 alone, according to a recent study, 21 countries shutdown or throttled internet and social media for a total of 27,165 hours, a 49 percent increase over the previous year, affecting some 268 million people. A shaped connection might clamp down (or even block!) certain types of traffic while letting other services run at the highest speed possible. So it’s easy for your ISP to see whether your internet packets are from web browsing, video streaming, torrenting, and so on. Different types of network traffic have different communications protocols. Shaping, on the other hand, is the practice of limiting connection speeds on a per-protocol basis.
