I prefer to save and use a local copy of the file anyway. Although I’m technologically fairly ignorant, I’m imagining that it negates a couple of possible issues. Firstly, there’s no problem if http://visualiser.maidsafe.net/safe_proxy.pac becomes unreachable. Secondly, it avoids relying on a central target should someone want to maliciously alter the file. Please correct me if I’m wrong because then I will learn…
