The Analytics service will be briefly unavailable on Tuesday Jan 16 due to some required maintenance. The maintenance will start some time between 3PM and 5PM. The maintenance itself should be ~20 min overall.
The Analytics dashboard will be unavailable for that time. The Validator within the Editor, the metrics displayed on the Developer Dashboard and the Raw Data Export API will also be unavailable.
There should be no data lost from this maintenance.
During this time, if you try to integrate Analytics from within the Editor, you may not receive confirmation that integration was successful. However, after the maintenance is complete things should work as expected.
I apologize for any inconvenience this will cause.
I will update this thread if there are any new information.
