I wrote a nice letter to DataCell about the bandwidth my Tor router was using and got a quick and good response. It also sheds some light on Datacell's(in Iceland) connectivity to the outer world.
" Bandwidth in Iceland is an issue in terms of most ISP's charge by the gigabyte transferred. This is the case because most ISP's depend on Vodafone or Siminn for their backhaul and those charge by the transferred Gigabyte on the international side while they don't charge for national transfer. They do that because they pay outrageous prices on the link to central europe and probably because they want to make a lot of money too ;-).
Our connectivity does not depend on them however. We managed to get a somehow acceptable price for international connectivity. Its still 5 times higher than bandwith in central europe but its at least not 50 times as high as the first offers we got.
At the moment we have excess capacity. Our links are loaded like less than 1%. Once we get more customer, the link will be filled up. Our infrastructure is configured to use fair queuing. This means that every IP in our network gets a fair share of the bandwidth which is the way we operate.
I don't mind having traffic on the excess bandwidth as long as all customers get their guaranteed part. If it would become an issue we would enforce it by using rate limits."
So, for now anyway, there doesn't seem to be a problem with my running nearly 100GB/day through my Tor middle router. The TOS excludes the running of open mail proxies doing anything illegal (by Iceland's laws), this to be expected. I can see nothing in the TOS would directly rule out Tor, at least a non-exit router. All my contact with DataCell has been very friendly, I'd recommend them to anyone who can afford ~US$70/mo. for a virtual server. Just remember that when in Iceland, never carelessly throw stones and be polite to the littl' people.
