I agree with you,
“ We are worried there is something behind this. Maybe someone figured out a way to use internet for suspicious or illegal activities?”
Its common view that the Internet speed has had a major impact upon criminality.
Internet throttling is when the ISP intentionally limits the internet bandwidth or speed. ISPs can throttle internet connections when someone is participating in illegal online activities.
As a matter of fact, no doubt a good internet speed is at or above 25 Mbps. ... Fast internet speeds, those in the 100+ Mbps range, are often better, especially if you want your internet plan to support multiple devices and users at once.
internet download speeds of 100 Mbps or higher are often considered fast internet because they can handle multiple online activities for multiple users at once without major interruptions in service.
