Issues Detected:
  • Guard: requires Stable flag : Guard flag requires having the Stable flag first
    Suggestion: Get Stable flag by maintaining consistent uptime. Stable requires uptime and MTBF at or above network median (typically 2-3 weeks of stable running).
  • Guard: WFU below threshold : Weighted Fractional Uptime 89.1% is below 98% requirement
    Suggestion: WFU measures recent uptime (recent downtime weighs more heavily). To improve: 1) Minimize restarts, 2) Use systemd with Restart=always, 3) Monitor for OOM kills, 4) Schedule updates during low-traffic periods.
  • Not eligible for Stable flag : Uptime or MTBF below network median for most authorities
    Suggestion: Stable flag requires uptime/MTBF at or above network median. Keep your relay running continuously for 2-3 weeks. Avoid restarts. Use reliable hardware and network connection.
  • HSDir: requires Stable flag : HSDir flag requires having the Stable flag first
    Suggestion: Get Stable flag by maintaining consistent uptime. Stable requires uptime and MTBF at or above network median (typically 2-3 weeks of stable running). Avoid restarts.
  • HSDir: requires V2Dir (tunnelled-dir-server) : HSDir requires the relay to support tunnelled directory requests (V2Dir flag). This relay is missing V2Dir — the descriptor likely does not include tunnelled-dir-server, usually because DirCache 0 is set in torrc.
    Suggestion: Remove DirCache 0 from torrc (DirCache is enabled by default in Tor ≥0.3.3). Restart Tor and verify the descriptor includes tunnelled-dir-server. You can check with: grep tunnelled-dir-server /var/lib/tor/cached-descriptors
  • HSDir: WFU below threshold : WFU 89.1% below 98% required for HSDir
    Suggestion: HSDir requires ≥98% WFU, Stable flag, and Time Known ≥25 hours (or ~10 days for moria1). Improve uptime consistency.
  • 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.
  • Write Bandwidth Limit Hit : Write rate limit (63 Mbit/s) was hit 6 times. Relay is throttling outbound traffic.
    Suggestion: Increase RelayBandwidthRate and RelayBandwidthBurst in torrc if your connection has more upload capacity.
  • Read Bandwidth Limit Hit : Read rate limit (63 Mbit/s) was hit 23 times. Relay is throttling inbound traffic.
    Suggestion: Increase RelayBandwidthRate and RelayBandwidthBurst in torrc if your connection has more download capacity.
Notes:
  • Rate Limit Configuration: Configured limits: Rate=63 Mbit/s, Burst=13 MB. Limits hit: Write=6, Read=23.

— = 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.
