% uptime is a terrible metric. Begin down for an hour in the middle of the day is only .14% downtime for the month but is typically regarded as a big deal. If it happened every single workday you're still looking at 97% uptime! Sounds wonderful, right? Just work around it for an hour per day!
Number of outages and duration total are much better metrics.
looking again, the reporting under 'API Requests' downtime seems accurate but none of the earlier outages report downtime under 'Git Operations', which were also broken.
didn't notice there was a selector for which type of downtime on that page that didn't default to all.
