A lot of advice on how to achieve "high uptime" focuses on the technical bits. The technical bits are important, but the bigger risk is the people component. I've been in this game for decades and I've seen time and time again that all it takes is one bad hire who likes to roll out changes carelessly, bypassing any change managememt board, to break your uptime SLA for the entire year. You can fire or discipline that developer after the fact but at that point it is too late. See for example: this year's Crowdstrike outage.
