Version
0.4.9.6 Recommended
Issues Detected:
  • Guard: bandwidth below threshold : Observed bandwidth 9 Mbit/s is below 2 MB/s minimum (AuthDirGuardBWGuarantee)
    Suggestion: Guard requires ≥2 MB/s bandwidth OR being in top 25% of network. To increase bandwidth: 1) Ensure adequate upstream capacity, 2) Check RelayBandwidthRate/RelayBandwidthBurst in torrc, 3) Monitor with Nyx or ARM.
  • 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). Self-reported uptime from 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.
