TorrentFreak has some nice technical details on Bahnhof, the Swedish ISP that hosts (among other things), Wikileaks. The firm responded to IPRED, Sweden's batshit copyright spying law, by switching off its logs, so that putative copyright holders would not get anything if they tried to use IPRED's easy-peasy sneak-and-peek warrants. Now that Sweden is about to adopt the EU's rules that require all ISPs to begin logging, Bahnhof will insist that all its customers use an anonymizing proxy, so it can no longer tell what its customers are doing. Customers who want to make it easy to be spied upon can opt out for about $8/month.
Since the service will encrypt user traffic, not even Bahnhof will know what their customers are doing online. If the ISP doesn't know about their activities, then there's not much to log. Nothing to log means there's nothing useful to hand over to authorities and anti-piracy companies.
"Technically, this is a stealth section, we will store all data up to this point of invisibility," adds Karlung, referring to the first-hop connection the customer makes with the company's servers when going online.
"What happens after that is not our responsibility and is outside Bahnhof. So the only thing we are going to store is very little information, which in practice will be irrelevant."
