Only if you get gigabit networking (which can transfer only so much in a month). If you get 10Gbit/s, it's not unlimited anymore.
> The included traffic volume for outgoing traffic is 20TB. There is no bandwidth limitation. Overusage is billed with € 1.00 ($ 1.20)/TB. Incoming and internal traffic is unlimited.
So only egress is paid on 10Gbit, but still.
