We will be doing a maintenance on the Cellar cluster starting on 2017-07-26 at 08:00 UTC.
This is the 2nd step of the maintenance started on the 20th (https://status.clever-cloud.com/incident/31).
This should not have an impact on availability but may have a slightly bigger impact on performance than the first step (which did not have any noticeable impact).
It should take around 10 hours. This is a very rough estimate though, we will be posting updates along the way.
EDIT 08:01 UTC: Maintenance is starting now.
EDIT 11:55 UTC: Everything is going smoothly. Performance impact is very low.
EDIT 19:35 UTC: Maintenance is still in progress. No significant impact; so as for the 1st step, consider this event over.
