The Internet is like a major highway system, the Internet Information Highway has many roadways and interchanges, each having their own capacity and speed limit. Similar to highways you get traffic delays. Just as you have to wait in a your car for a traffic light, data sent to your computer has to wait while other data passes through routers, switches, and hubs (The Internet equivalent of an intersection).
Internet traffic during peak hours tend to lead to slower internet connections. When fewer people are online, such as after 11 p.m. and before 7 a.m. you’ll typically notice faster internet connectivity.
