A minute counts as failed only when two or more regions failed the check; the percentages are the minutes that did not. Failures in one region are counted apart: our checks saw them on 66 of these 90 days, 694 minutes in all, and a day with 30 or more such minutes is a disrupted day.

Slowest 5% of checks (p95)Typical check (p50)Flagged above: twice the usual time

Before 2 Nov, each day’s figures come from its last hour or two only. A day is flagged as slow only when its slowest 5% of checks take more than twice their usual time (the median of the previous 30 days). 2 days were above that line in the last 90 days. Above the chart: on 13 Oct some checks hit the 6-second timeout.
