Keeping a VPS quiet
Most small servers fail not because of traffic but because of drift: unpatched packages, forgotten timers and configuration that nobody can explain a year later. A short weekly review is usually enough to keep things predictable.
Nordlys Notes
A small collection of engineering notes about networking, self-hosting and keeping small services boring.

When a network path behaves strangely, capture the traffic first. Handshakes, retransmits and timing tell the story far more reliably than a stack of guesses.
Write it down
A note that says what runs where, and why, saves more time than any automation you will write later.
