Version
0.4.9.1-alpha-dev Not Recommended
Issues Detected:
  • 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.
  • Tor version not recommended : Running Tor version 0.4.9.1-alpha-dev which is not on the recommended list.
    Suggestion: Update to the latest stable Tor version. Outdated versions may have security vulnerabilities and could eventually be rejected by the network. See torproject.org/download for latest releases.
  • General Overload Active : Relay reported general overload at 2026-01-07 15:00 UTC. This indicates OOM killer invocation, onionskin queue saturation, or TCP port exhaustion.
    Suggestion: Check CPU/memory with htop. Review logs for "out of memory" or "onionskins" warnings. Consider increasing MaxMemInQueues in torrc. Verify TCP ports available.

— = 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.
