Hi all,
I'm running an exit relay and seeing a strange discrepancy between bandwidth
authorities. Some measure my relay without any problem, while others fail every
single attempt with stream errors.
Relay: beacon
Fingerprint: 85082CD18CF6C931968105DFFFDDE82EBC4C9AF8
Observations from 2026-07-22:
moria1 (13:47 UTC) — success=3/3, error_stream=0, error_circ=0, bw=6400
tor26 (06:23 UTC) — success=1/3, error_stream=0, error_circ=2, bw=1
maatuska (14:21 UTC) — success=0/26, error_stream=26, error_circ=0,
unmeasured=1, vote=0
longclaw (09:32 UTC) — success=0/7, error_stream=7, error_circ=0, unmeasured=1,
vote=0
gabelmoo — no data for this relay
What stands out: error_circ is 0 at both maatuska and longclaw, so circuits
build fine. The failures happen at the stream stage, and they happen every
single time. Meanwhile moria1 measures the same relay flawlessly on the same
day.
Configuration:
ExitRelay 1, ReducedExitPolicy 1, IPv6Exit 1, RelayBandwidthRate 37 MBytes,
RelayBandwidthBurst 42 MBytes
What I have checked locally, without finding anything:
- DNS: local Unbound resolver, 0 serverfailed, 0 refused, 0 truncated, 213
timeouts out of 4920 queries (~4%)
- IPv6: globally routable, verified from outside
- MTU: full 1500 bytes pass unfragmented on both v4 and v6, no packet loss,
~6ms latency
- TCP: ListenOverflows 0, ListenDrops 0, PruneCalled 0, conntrack 710/65536
- File descriptors: 65536 limit, ~620 active connections
- OOM: tor_relay_load_oom_bytes_total 0 across all subsystems
- Onionskins: 0 dropped
- Firewall: outbound policy ACCEPT, nothing blocked
- Tor logs: no warnings or errors over the past several days
- System clock: synchronized via NTP
The relay is relatively young (relay_in_recent_consensus_count between 28 and
85 depending on the authority), so I'm also open to the possibility that this
simply resolves itself with more measurement attempts over time.
Thanks,
beacon
