First of all there is no such thing as Unlimited bandwidth, it is a myth. There may be some hosts that advertise it but send an account to them like this where someone actually starts to use a lot of BW and see how long they last.
Secondly if you want a host that would love to see you burning high amounts of BW (so long as your ROI increases then it is always a great thing) then hit me up about what
Caro.Net has to offer, you won't go wrong on the network home of AEBN.
Also, for your high BW projects take a look at our
Caro.Net Unmetered Packages !
