Steam download super fast?

[NunoLava1998]

I'm actually complaining about a good thing here; I was reinstalling Cities Skylines on Steam, then suddenly the network speed went "f*ck you" and literally went 30 megabytes/s per second. Literally 50% of my download was done in like half a minute, while the other part took around 10-20 minutes. Why did this happen, especially because that's 240 megabits/s per second and my connection is supposed to be 100 megabits/s, and that speedtest only showed a 55 megabit/s connection.

 

How the f*ck did this happen?

Is it possible some of the game data was ready since it was a re-install?

I uninstalled it and installed it using Steam. That might be why, though.

It has happened to me a few times, and that was re-installations too. I can't think of any other reasoning behind it.
