Thanks to appliedprivacy for the update on outreach with Hetzner, and to everyone sharing operational experiences.
A few clarifications, grounded in Tor Project guidance:
- Temporary relay unreachability due to outages is an expected operating
condition, and Tor is designed to adapt to changing relay availability
https://community.torproject.org/policies/relays/expectations-for-relay-operators/
- Tor’s community resources note that relay operators should “try to avoid
the following hosters,” listing Hetzner, based on documented operational
friction reported by relay operators
https://community.torproject.org/relay/community-resources/good-bad-isps/
- For context, there were two events: emergency maintenance before Christmas,
and an outage before New Year’s; root cause is still under investigation, with
only a physical link loss on provider equipment confirmed so far.
- Raw relay counts are a poor proxy for concentration risk, which Tor already
models via families, bandwidth weighting, and path selection.
- Tor guidance also notes in Section 3 of the Expectations for Relay
Operators:
“Don’t block outgoing connections. Tor relays need to be able to reach all
other Tor relays.”
