What we write

Clear, practical notes on web performance, uptime and reliability. No filler, no hype, just writing worth your time.

Why it exists

The web breaks in interesting ways. This is a place to write down what we learn about keeping it fast and online, in public.

Who it is for

Developers, ops folks and anyone who cares why a page is slow or a service is down, and what to do about it.

The approach

Written to be read once, and understood.

404Pulse is a journal of guides and notes on the web, performance and uptime, written plainly and tested against how things actually behave.

No trends for the sake of trends. Just the things worth knowing when you are responsible for keeping something online.
