The point of the status page is so you can point to it for your five nines SLA and go "look? we were only down for one hour". As soon as the money relies on the metric, the metric will reflect the money.
Despite their update, I like how they're saying only their recursive DNS had "degraded performance", while authoritative is "operational". The entire reason everything blew up was because their authoritative nameservers weren't responding.
I mean, I guess your entitled to look at it that way, but I don't think it's dishonest of them to distinguish between "nothing is working" and "some regions aren't working".
Ahh I remember when AWS went down (think it was 2 years ago now?) or at least a data center in us-east? Majority of the internet went down and status page went down as well. Man good times.
Status pages are a marketing channel not a channel for developers most of the time. It most likely has to go through some layers before someone updates the status page.
