It's probably a local resource, because the bandwidth authority measurements don't vary much, even though the bandwidth authorities are on two different continents: https://consensus-health.torproject.org/consensus-health-2019-04-07-20-00.html#855BC2DABE24C861CD887DB9B2E950424B49FC34 > To work out where the limit is, run another Tor instance. > > You could also wait another week to see if your relay picks up another 5-10% > traffic increase. > > T >
