$70 per month seems low for 1 Gb/s service here in the USA.
The Comcast rate for 5 or 7 Mb/s down service where I live is almost $50 per month if you already have their minimal cable TV service ($23). On top of that most people have to rent a data modem at $7 per month. HD TV with more channels can greatly increase that price. The Comcast 105 Mb/s data service is $200 per month.
