1. The Power Outage That Didn’t Stop Us
Our Fremont office went dark. Completely dark. There was a power outage and our provider failed to give us a heads-up, so it took us by surprise.
No power meant routers, ESXi hosts, Proxmox servers, backup systems, and even Wi-Fi were knocked offline. It was a total blackout.
But we weren’t scrambling. We had architected a true out-of-band path using LTE. Even with the production network down, we still had a way in.
From miles away, we diagnosed the problem, rebooted critical infrastructure, and got things running again before most people even noticed.
Lesson: Your recovery plan is only as good as your last mile. If your failover path isn’t truly independent, it’s not a plan – it’s wishful thinking.
