Please let me know if you have any reason why we should not proceed with this planned maintenance. As always, we aim to keep downtime to as little as possible, but unexpected complications can arise causing longer downtime periods than expected. All systems should be operational by the end of the maintenance window.

Feel free to comment directly in those bugs if you see issues past the planned downtime.
