_Uptime: Derived from the incidents the vendor posted on its own status page, not measured by us. A minute counts as an outage minute when a major or critical incident (as the vendor labelled it) was open; incident minutes include minor ones too. Maintenance and incidents marked "no impact" are left out, overlapping incidents are merged, a resolved incident counts for at most 7 days, and one still open with no resolution counts for at most 24 hours._
