A graph I have to question is even accurate.

> Across 170 days with at least one incident · worst day Thu, Nov 20, 2025 (1.1 days)

1.1 days total how is that possible? Scrolling over that day doesn't indicate the math behind the scenes - 1.3 hours single bullet point.

Also Nov 19 has a bullet point 1.3 day outage but total is 8.1 hours

The missing status page [1] treats it as downtime any time any component of the system is down, and calculates the overall uptime based on the time that doesn't overlap with any individual category outages, and the overall downtime as any time overlapping with at least one individual category outage to avoid double-counting They show 24h of minor outage on that date.

I'm guessing that this site is taking the downtime in a given day across all services and adding it up, which would mean the worst possible day has 10 days of downtime (a day of downtime for each major category).

I see a bullet point for "1.0 days of 1.3 days", and when I mouse over the previous day (Wedensday 2025-11-19), I see "7.8 hours of 1.3 days".

I haven't actually checked any sources to confirm there really was downtime on those days, but if we assume those numbers are true 7.8 hours + 1 day is about 1.3 days.
