On 2019-01-18 at 13:11 CEST / 07:43 EST, we received reports about the heatmap view being broken. Our engineers identified an issue caused by an earlier deploy, which broke the rendering of Heatmaps.
Why did this issue occur?
A coding error on our Heatmap viewer was introduced during an update to our Heatmaps, that caused a front-end error to prevent the Heatmap from being displayed.
What effect did this issue have on my site?
None. This only affected the viewing of Heatmaps.
What effect did this issue have on my data?
None. All data was collected as usual.
What are we doing to ensure it doesn’t happen again?
Further investigation into how this passed testing will be done, to ensure a more reliable deployment of new features and fixes.
