Very often I can watch videos in Full HD on YT, browse Instagram without any problem but can’t browse some apps or play some games, even though when I test the internet speed it says that it’s very fast.
In: Technology
* Everything the uses the internet is based on a server device somewhere that sends you the information you request from it.
* The pathway between your device and that server is different for each server you need to contact and thus the speed with which you can get data from that server will be different.
* Also the load on that server at the time you are trying to use it can slow things down.
* Again each server is different and each app likely uses different servers.
* Lastly a speed test only tells you the speed between your device and the speed test server.
* The reason they are useful is because it can tell you the theoretical max speed your internet service provider is *allowing* you to connect to the internet at.
* Speed test servers are also designed to be super fast and don’t do anything other than speed tests so they have very good performance.
