Hetzner root servers get traffic for other machines by @_vere

Retrospective Overview & Key Insights

Distilled reflections, business mechanics, and tactical takeaways:

In this technical retrospective (2025), @_vere shares practical architectural lessons learned from running, scaling, or migrating production software under lean constraints.

Core Principles for Independent Builders:
1
Defaulting to simpler architectures (such as monolithic frameworks, SQLite, or managed VPS) prevents early engineering bankruptcy.
2
Evaluating true compute and egress costs reveals that high cloud bills can often be slashed by 80%+ through judicious re-platforming.
3
Code you write at 2 AM as a solo engineer must be easy to debug six months later without complex microservice dependencies.
Community Debate Themes:

HN engineers debated the tradeoffs between cloud convenience and raw server economics, database indexing strategies, and resisting premature architectural complexity.

OP @_vere Original Author

We have independently confirmed that we are getting traffic designated for other servers on our serverauction root server at hetzner. Pretty sketchy feeling to have this be the case for a hoster on the scale of hetzner.

Hi there HN readers, I checked with some team members. They are aware of this behavior and have told me that it does not cause a security risk. If you have any additional questions or concerns, please write a support request using your account. --Katie, Hetzner

Tje only time i had problems with wrong traffic were when domain owners didn't update their records for decommissioned servers.

How is this a problem? Every network interface should be treated as public, meaning you must use encryption and firewall rules.
