Here we go – tomorrow marks the start of what we've been gearing up for all week: The UPS switch-out, a complete power cycle of the entire server farm, and the meticulously planned on/off sequencing of our machines. I'm all set for it too.
I've wrapped up an extensive analysis to determine which machines require a "fresh start." Plus, I've uploaded my ssh key to the systems I hadn't accessed yet – let's hear it for the ever-reliable bash loops! With that, I believe I've completed my share of the prep work.

This weekend promises to be a rollercoaster of emotions, meticulous checks, and in-depth analysis. We'll be rebooting servers, performing dump and recovery operations on databases, and issuing the dreaded kill -9 to applications, among other tasks.
But rest assured, everything is under control. We've got a strong team, and we won't be short on watchful eyes or skilled hands. My bottle of CBD is at the ready, just in case. I'm ready too, well, almost ready.
