This helps tremendously--thank you. For the most part then it appears the consensus bandwidth values assigned to the relay here are within reasonable expectation allowing for the methodology. Lately have been seeing fairly stable and moderate number of 225k vs the local 495k calculation. Next ti

The bandwidth authorities assign all kinds of wildly incorrect capacities to the Tor node here. The Tor relay software has been up for 45 days and has not been down for more than five minutes for three or four months. Occasional outages from the ISP mucking with their network, but nothing more th
