Recap of yesterday‘s session: Useful metrics for Tor Browser • information of which transports work in which countries: let users pick a country and then provide transports that likely work • automated reachability tests of hard-coded default bridges • OnionPerf vs. OONI throughput test
Add new graphs to Tor Metrics: vanilla Tor • OONI could add a daily task that produces a CSV file with number of measurements by country and day that worked or timed out; fields may include: ◦ date ◦ country ◦ number of networks as a confidence metric ◦ successes ◦ unknowns (timeouts, failures, other issues) • Plus a non-aggregated version including ◦ time to bootstrap ◦ ooni report ID
Add another graph to Tor Metrics: Bridge reachability test • basic connectivity test, not Tor connection • challenge: default bridges might go down for days
How can OONI make better use of Tor Metrics data • Look at reported user numbers by single relay/bridge
