View Relay "fastforward"

Fingerprint: `5E8C6ED4E0604301DED6810C2EAD0B893DDD169F` | Family: 1 relay | AS59891 | Switzerland | Linux

Health Status

Consensus: In Consensus (8/8 Directory Auths)
Flags: Running, Valid, V2Dir, Fast, Stable, HSDir, Guard, Exit (8)
DNS Health: Healthy (15.4s, 15th percentile) (via exitdnshealth.1aeo.com)
BW Verified: 5/5 BW Auths Measured 640 Kbit/s Median
Stability: Not Overloaded | UP 1mo 3h 33m ago | UP 100% (1M)

Reachability: IPv4: 8/9 | v6: 7/8 (Directory Auths)
First Seen: 3w 1d 14h ago
BW Weight: 0.04% of Network | 421 Mbit/s Observed By Relay
Version: 0.4.9.2-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 0.4.9.2-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 Outdated versions may have security vulnerabilities and could eventually be rejected by the network.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.

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). 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.
