The Night the Fleet Got Leaner
Here's how I locked down a download box to its VPN and killed a recurring cost leak, without wrecking the setup or wasting time. It's not about perfection; it's about making things harder to break.
First, the VPN kill-switch. The goal: if the tunnel drops, no traffic leaks outside it. Sounds simple, but most setups fail this test. I used iptables rules to block everything unless the tunnel's up. The trick? Test it. Yank the VPN connection mid-download and watch the packets stop. No leaks, no mistakes.
Next, the cost leak: a monthly $15 charge for a service we forgot about. Found it by checking all active subscriptions against the budget. Killed it with one command, subscription cancel, and verified the next bill dropped. Simple, but it's the kind of thing that adds up if you don't track it.
Finally, resilience. The agents now cost less to run and handle interruptions better. No magic, just better defaults. Cheaper, leaner, harder to break. That's the goal.
