On 25th July, 2020 at 5:30 UTC our engineers identified an issue with Heatmap creation and Signups not working correctly.
New users were unable to complete signup, while existing users were unable to create new heatmaps.
After an earlier database update, an extension to the database was not properly loaded and prevented the table for new heatmap data to be created. During signup we automatically create an initial heatmap and since this failed the entire signup failed.
We will hold an internal postmortem to identify potential improvements.
