We are in the process of restoring the missing events to all affected environments. Once that is done we plan to trigger an update of the data in the warehouse, which should bring everything back to normal.

We have identified that analytics events between approximately 19:25 on the 13th September and 23:40 on the 19th September failed to load into the data warehouse. We are working on restoring the missing events. Events outside this time window are unaffected.

We have identified an issue whereby some events are missing from our data warehouse. This is causing some of the engagement dashboard stats to be incorrect (under-counting). For the time-being, please assume that the data on these dashboards is incomplete.
