We will never have perfectly accurate bandwidth allocations. So I think we need to decide how much inaccuracy we are willing to tolerate in the bandwidth system. (Currently, we tolerate 30-50% variance between bandwidth authorities. But we don't have any good way of working out the difference between the median measured bandwidth, and the actual bandwidth of a relay.) Once we know our tolerance, it will help us prioritise fixing guardfraction. It will also help us evaluate bandwidth authority configurations and implementations. > But when considering the guardfraction feature, we should think not just about the code on the Tor side, but also about what feels to the dir auths like yet another pile of abandonware crap that they're going to be asked to run and maintain forever. > > So, if we're thinking about the feature's future, let's not underweight the importance of the external portion of the tool too. +1 -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/24456#comment:16> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
