Issues Detected:
-
Guard: requires Fast flag
: Guard flag requires having the Fast flag first
Suggestion: Get Fast flag by having bandwidth ≥100 KB/s OR in top 7/8ths of network. Most relays get this easily. -
Guard: bandwidth below threshold
: Observed bandwidth 2 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. -
HSDir: requires Fast flag
: HSDir flag requires having the Fast flag first
Suggestion: Get Fast flag by having bandwidth ≥100 KB/s OR in top 7/8ths of network. Most relays get this easily. -
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. -
General Overload Active
: Relay reported general overload at 2026-07-24 23:00 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.

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.
