Ping me.
I read everything that arrives and reply to anything that deserves a reply. No form, no funnel, no autoresponder. Just an address that reaches me directly.
Worth writing to me about
A platform decision you are weighing
Self-hosted or managed, where the isolation boundary belongs, what to do about state you cannot rebuild. I am glad to think out loud about these, and I will say so when managed is the better answer.
A network that is behaving strangely
Particularly the partial failures: paths that are up but lossy, convergence that takes longer than it should, symptoms that present two layers above the cause.
Something here I got wrong
If a post on this site is mistaken or has aged badly, I would rather hear it from you than leave it standing. Corrections are welcome and get credited.
Speaking, writing, or working together
Meetups and conferences, a piece for your publication, or a problem your team is stuck on. Based in Berlin, comfortable remote.
Following the writing
New posts go out over RSS, which works today and asks nothing of you. An email edition will follow once there is enough of a rhythm to be worth committing to. Write to me if you want telling when it starts.
