Family: 4 relays | [email protected] | AS51290 | Poland | Linux

Health Status

Consensus: In Consensus (9/9 Directory Auths)
Flags: Exit, Fast, Running, Stable, V2Dir, Valid (6)
BW Verified: 5/6 BW Auths Measured 184 Kbit/s Median
Stability: Not Overloaded | UP 2d 5h 21m ago | UP 88% (1M)

Reachability: IPv4: 9/9 | v6: 7/7 (Directory Auths)
First Seen: 2y 5mo 3w ago
BW Weight: 0.01% of Network | 177 Mbit/s Observed By Relay
Version: 0.4.8.21 Recommended

Issues Detected:

Guard: WFU below threshold : Weighted Fractional Uptime 96.4% 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.
HSDir: WFU below threshold : WFU 96.4% 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.

Consensus Evaluation

Data from Tor CollecTor (authority votes, fetched 2026-01-29 08:45:07).

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: 0/9
Reachability: IPv4: 9/9 | IPv6: 7/7 (2 don't test)
Consensus Weight (Dir. Auth.): Median: 184.0 Kbit/s | Min: 80.0 Kbit/s | Max: 224.0 Kbit/s [Warning] High deviation
Identified Issues:
- Guard: WFU below threshold: Weighted Fractional Uptime 96.4% 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.
- HSDir: WFU below threshold: WFU 96.4% 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.

— = 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.
