Four routes, so your message reaches the right place. Corrections from people who have run this in production are the most valuable thing we receive.

Corrections and technical feedback
If something on this site is wrong, incomplete, or true in general but wrong in a case that matters, we want to know. Please include the page, what it says, and what actually happens in your environment — including versions, because a claim is often right for one release and wrong for the next.
Material corrections are noted on the page itself rather than edited in silently. See the editorial policy.
Security reports
Security issues in this site or its tools should be reported privately before public disclosure. Mark your message as a security report and include reproduction steps. See security for what to include and what we ask of you.
Expert services
For consulting engagements — OpenStack, Kubernetes, Terraform, observability, infrastructure architecture, or incident review — see expert services for scope, then get in touch with what you are trying to achieve and the current state of the system.
Everything else
Questions, requests for coverage of a topic, speaking, or anything that does not fit above.
We read everything. We do not accept guest posts, link insertions, or sponsored placements in technical content, so those messages will not get a reply.
Contact routing
Contact addresses are being set up as part of launch. Until they are live, this page deliberately does not show an address rather than showing one that bounces.
If you are the site owner: add the routing addresses here and remove this notice before launch. The launch quality gate checks for it.
