Oh man that NOC engineer was probably running on 2 hours of sleep and stale coffee too. Ran into a similar thing at a previous job where our backup DNS server had a bad cache file from the last admin who left in 2017. When the primary DNS took a dirt nap the secondary started serving up totally wrong IPs for half our internal apps. The whole failover test thing is like going to the dentist - everyone knows they should but nobody wants to actually do it. We finally started doing quarterly "break stuff on purpose" days where we'd kill a primary system during lunch and see what actually happened. First time we did it a backup storage array just flat out refused to take over because the replication job had been silently failing for 8 months. Now I check failover configs every time I patch anything just out of pure paranoia.

Two hundred fifty pages is barely scratching the surface in a genre built on slow burns and layered reveals. Those first few chapters are basically the prologue where the author is still setting up the dominoes, and the real payoff usually kicks in around page 400 or later. If you bail at 250, you're missing the entire point of why fantasy exists, which is to let the world sink in until you can't remember the real one.

Sometimes running it through a cold air return works better than the wall.

Smell it before you use it, that's my rule now. I had a bottle of Rodinal that went funky on me once, turned into something that looked like swamp water and smelled like a dead fish left in the sun. The negatives came out all cloudy and muddy, like someone took a photo through a dirty window. Learned that lesson the hard way, now I check my chemicals like I'm sniffing milk before a cereal pour, lol.

I heard from a buddy that Aruba Central's licensing got more strict last year, so watch out for hidden costs. The AP density thing is real though, I read their controllers scale better than Meraki on paper. Both platforms work fine for 10 sites, but you'll probably have a smoother rollout with what your guys already know.
