My first (fast) internet connection was 1 Mbit.

We had 1gb to download per month. This cap disappeared when more competitors showed up though (i had that cap around … 2001)

I havnt seen a data cap for internet connections since. I am not aware of any either. Except for mobile phones. Though, they also have unlimited data for those , if you want. (I have. Just so i never have to worry about it ever again)
