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.
Last updated 25 September 2026
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.
Use the form below and pick Something else, quoting the page URL.
Security reports
Security issues in this site or its tools should be reported privately before public disclosure.
Use the form below, pick Something else, and begin your message with SECURITY: so it is
triaged first. Include reproduction steps. See security for what to include and what
we ask of you.
To be straight with you about response time: this is a form read by one person, not a staffed security inbox, and no response-time commitment is made. For anything time-critical affecting third parties, do not rely on this channel alone.
Expert services
Two bounded reviews are defined with their inputs, deliverables, and limits on expert services: an Infrastructure Change Review before a risky change, and an Incident and Reliability Review after one.
Read the scope, then request a scoped review. Price is quoted per engagement — none is published, because none has been set.
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.
How messages reach us
Every route above goes through one form, which records your message where it will be read. Choose the closest option in the Which review field — including Something else for corrections, security reports, and general questions.
There is no published email address yet. Rather than show one that bounces, the form is the channel, and it tells you on screen that your message was stored and gives you a reference.
Outbound email is not configured on this site yet, so you will not receive an automatic confirmation message. Keep the reference the form gives you.
