BW Weight: 0.00% of Network | 17 Mbit/s Observed By Relay
Version: 0.4.9.5 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.
Write Bandwidth Limit Hit : Write rate limit (17 Mbit/s) was hit 5,651 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 (17 Mbit/s) was hit 4,037 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=17 Mbit/s, Burst=34 Mbit/s. Limits hit: Write=5,651, Read=4,037.

— = 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.
