I've heard this so many times and not seen it contradicted so I started saying it myself. Even my last Ops team wanted to run some things in us-east-1 to get prior warning before they broke us-west-1.
But there are some people on Reddit who think we are all wrong but won't say anything more. So... whatever.
Nothing in the outage history really stands out as "this is the first time we tried this and oops" except for us-east-1.
It's always possible for things to succeed at a smaller scale and fail at full scale, but again none of them really stand out as that to me. Or at least, not any in the last ten years. I'm allowing that anything older than that is on the far side of substantial process changes and isn't representative anymore.
