View Relay "zgato"

Family: 1 relay | [email protected] | AS7489 | Singapore | Linux

Health Status

Consensus: In Consensus (5/9 Directory Auths)
Flags: Fast, Running, Stable, V2Dir, Valid (5)
BW Verified: 2/6 BW Auths Measured 20 Kbit/s Median
Stability: Not Overloaded | DOWN 16h 45m 43s ago | UP 99% (1M)

Reachability: IPv4: 5/9 (Directory Auths)
First Seen: 1mo 3w 6d ago
BW Weight: 0.00% of Network | 20 Mbit/s Observed By Relay
Version: 0.4.8.21 Recommended

Issues Detected:

Guard: WFU below threshold : Weighted Fractional Uptime 96.8% 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 96.8% 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.
Low bandwidth authority measurements : Only 2/6 bandwidth authorities measured this relay. Minimum 3 measurements needed for accurate consensus weight.
Suggestion: Low measurement count can indicate connectivity issues. Check: 1) Relay is reachable from multiple geographic locations, 2) ORPort accepts connections from bandwidth scanners, 3) RelayBandwidthRate in torrc matches actual capacity. New relays may take 1-2 days to be measured by all authorities.

Notes:

— = 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.
