# Maintenance Windows

Maintenance windows are a scheduled period of time when hardware, network, software, or configuration changes can be applied, and processes can be restarted.

For Foundation Tier customers, maintenance windows are predefined by region.

For Power Tier customers, maintenance windows are customer-selected.

Notice is provided to customers in advance of maintenance. CloudDBA customers are asked to confirm maintenance prior to scheduled start.

## View Current Maintenance Window

For Foundation Tier, to view the maintenance widown, Go to "Your services" and then "Details".

On Power Tier, to show the current maintenance window for a service:

1. Go to "Your services" page (top choice in left navigation).
2. Click the ">" to the left of the desired service.
3. The current maintenance window is shown in the "Customization" section.

## Choose Maintenance Window

A maintenance window selection applies to all services within a region.

For Power Tier customers, maintenance windows are customer-selected:

Maintenance windows can be updated at time of service launch, or on-demand:
