So, a few days ago I thought: “Hey, let’s be cool, ditch Apache, and hop onto the Nginx hype train because… HTTP/3, baby!” πŸŽ‰

Fast-forward to today, when I decided to show off and run one of those fancy SSL / web server grading tools. You know, the nerd’s equivalent of flexing in front of a mirror. 😎

…and then BAM πŸ’₯: my blog was completely invisible over IPv6. Like, gone. As if Thanos snapped half the packets away. 🫰

The Plot Twist πŸ”’βž‘οΈπŸš«

Turns out, my firewall had been the overzealous bouncer at the club, blocking DHCPv6 packets at the door. So my poor server never even got its global IPv6 address. No wonder it ghosted the Internet. πŸ‘»πŸŒ

The Strato Side Quest πŸ•ΉοΈ

While digging through the mess, I stumbled across a couple of β€œtiny oopsies” on my other Strato VServers. Most likely casualties of my great migration from Virtuozzo-based servers to KVM ones. (Yes, I typed that correctly on the first try. I swear.) πŸ§™β€β™‚οΈ

Luckily, those were easy fixes. But let’s be real: finding these bugs was more luck than skill. Like discovering you still had pizza in the fridge at 3 a.m. πŸ•βœ¨

Lessons Learned (aka “Dear Future Me”) πŸ“

  • Automate. EVERYTHING. – If it can be scripted, it should be scripted. My Ansible playbooks are now screaming for attention. πŸ€–
  • Test like a maniac. – Don’t just assume stuff works because β€œit worked yesterday.” That’s how future-you ends up crying in log files. 😭
  • IPv6 is not optional anymore. – Unless you like watching parts of the Internet slowly slip away while you yell at your firewall. 🌐

Final Words of Wisdom πŸ§™β€β™€οΈ

If today taught me anything, it’s this: server administration is 20% configs, 30% Googling errors, and 50% muttering β€œwhy tho?” at your screen. πŸ”₯πŸ’»

Now, excuse me while I go update my Ansible scripts before I forget again… because one day I’ll thank myself. Or at least curse myself less. πŸ€“
