We've spoken to a few Comcast relay operators with similar issues. https://lists.torproject.org/pipermail/tor-relays/2019-June/017376.html Adding more tor instances on networks like Comcast would only slow down Tor. >> The real answer is to fix the bandwidth measurement infrastructure. > > Do we have funding to continue to improve the bandwidth measurement > infrastructure?
