Most likely he used some VPN solution, I never could find the anonymity solution that he was using though. He had CCTV cameras positioned outside of the flat in the hopes that he could spot the party van before the feds smashed his door down, but it didn't save the day for him because he was distracted on IRC. He should have had his doors and windows hooked up to an alarm system and configured his PC to shut down into a memory wipe as soon as a breach was detected. This is merely one case of police pwning someone with FDE, there are other cases where they actually did cold boot attack after the suspect had managed to shut down his computer, but not enough time had passed for the RAM to clear. You probably will not have anywhere near a minute after your door is battered down, LE can get access to the blueprints of your house and use various techniques to guess the room that your PC is in, so they pretty much know exactly where to go. Also they have adrenaline pumping and are going full speed and the door will be on the ground when the front runners hit it the first time if they use a battering ram and then the rest of the team can just keep running full speed into the home and to the location they are trying to get to. five to ten seconds after you hear the door hitting the floor is a more realistic amount of time imo.
