Optimum Speed Test (Cablevision, Suddenlink)Īre we missing the official internet speed test site for your ISP or service? Let us know the name of the ISP and the link to the bandwidth test, and we'll get it added.Charter Speed Test (Spectrum, Time Warner Cable).CenturyLink Broadband Speed Test (Quest).Here's more on the official internet speed test sites for a number of popular internet service providers: While it's possible that some of the other more generic speed tests further down our list are technically more accurate, it'll be a hard case to make to your ISP that your service isn't as fast as it should be unless you can show the same with the bandwidth tests they provide. There is nothing you can do about this.Īt some point, you are not testing your connection, but the connection between the various networks that make up the internet between you and the destination.Testing your internet speed between you and your Internet Service Provider is the best way to go if you're planning on making an argument with your ISP about your slow internet connection. You are (from a network standpoint) closer to one of the speed test servers and overall less congested connections than the other. This app will show just how many 'networks' your traffic would need to pass through to get from you to its destination. To show this, you can use something called traceroute. THEY are in a different place with a different path. This is the main reason why different speed tests give you different results on the same device/connection. Now, lets say the speed test server is not only in a different region, but a different ISP. If the speed server is still on Verizon, but in a different region, my traffic would hit a bottleneck where the 2 networks meet and would have to compete with all the other traffic trying to get past the same bottleneck. If I speed test to a testing server also in the NY region on Verizon's network, I would get 1gig with no issue. Lets say I live in NYC, and have 1GBPS Verizon.

The internet is a series of connected networks.
