I was going to link the appropriate XKCD where organised attackers are panicing as they realise they're dealing with a sysadmin muttering about uptime..
At least that's accurate. "Degraded performance" would imply to me that things are functional, but slow. increased error rates can be anything from "try again" to ":shrug:"
Yeah, I also wrote a bot that chooses to create a status incident with the lowest key neutral message when it detects continued healthcheck fails (outside of maintenance) that steps in if an operator hasn't already created an incident. Maybe they're too busy fixing.
"some users may experience degraded service" => site completely down for all locations
