Also: uptime percentage must be computed as the intersection of uptime across services, not the union.
GitHub Actions: 98.31% uptime. We say something like: GitHub Actions: 12 hours affected in the last 30 days (98.31% uptime).
Normal people have no understanding of percentages or numbers, I agree saying 12 hours of downtime is more useful, but I’m also tired of trying to contextualize numbers for the numerically illiterate.
