We made a couple of tweaks to the Check statistics page based on customer feedback and to address some performance issues.

  1. We now show the 24 hour, 7 day and 30 day success ratio KPI's to give a better short term / long term view on the health of your checks.

  2. We've add the 99 percentile response time to the per location response times chart to give you a better view on how response time are distributed for a specific data center location.

Under the hood, we tweaked query performance and aggregation performance which results in a 70% performance gain.
