What reaches me fastest
- Corrections. Include the article URL and the exact sentence or figure you believe is wrong, plus a source if you have one. These get priority.
- Questions about a note. Include what you have already tried and the platform or release involved.
- Privacy requests. Tell me what data you are asking about; this site has no accounts and no forms, so there is usually very little to look up.
- Professional enquiries. Architecture reviews, network design, and senior network architect or technical lead roles.
Response times
I read everything and reply within one business day. Technical corrections get an answer within three business days. If a message needs real analysis I will tell you when I can get to it rather than leave it unanswered.
What this site does not do
There is no contact form, no newsletter and no account to create — the site is static pages plus advertising. Sending email to the address above is the whole mechanism. Nothing you type on this website is submitted anywhere.
