Consensus Evaluation

Data from Tor CollecTor (authority votes, fetched 2026-01-29 11:45:07).

  • Consensus Status (need ≥5/9): In Consensus — 9/9 authorities voted.
  • Flag Eligibility (need ≥5/9 for flag): Running: 9/9 | Valid: 9/9 | V2Dir: 9/9 | Fast: 9/9 | Stable: 9/9 | HSDir: 0/9 | Guard: 9/9
  • Reachability: IPv4: 9/9 | IPv6: 7/7 (2 don't test)
  • Consensus Weight (Dir. Auth.): Median: 80.0 Kbit/s | Min: 43.2 Kbit/s | Max: 440.0 Kbit/s [Warning] High deviation
  • Identified Issues:
    • High consensus weight deviation: Large variation in Consensus Weight values across authorities (see 'Cons Wt' column in Per-Authority Details below)
      • Suggestion: Consensus weight measurements vary significantly between authorities. This can affect traffic distribution. Ensure stable network connection and consistent bandwidth availability.

— = not tested/available • Format: relay value | authority threshold • WFU = Weighted Fractional Uptime • TK = Time Known

Bandwidth Values Explained:
Relay Reported = Your relay's self-reported bandwidth from its descriptor (observed_bandwidth). Used for flag eligibility (Guard, Fast).
Authority Measured = Bandwidth measured by authority's sbws scanner. Used for consensus weight (path selection probability).
Why different? Authorities verify your reported bandwidth independently. 6 of 9 authorities run bandwidth scanners; 3 use relay-reported values directly.
Stable Uptime (Two Data Sources):
Relay Uptime = From Onionoo API (last_restarted field). This is your relay's self-reported uptime from its descriptor. Same value for all authorities.
Authority Threshold = From CollecTor vote files (flag-thresholds stable-uptime). Each authority may have different thresholds.
Why two sources? Vote files contain authority thresholds but not per-relay uptime values. Onionoo aggregates relay descriptors which include uptime.
