+Your application may also disconnect from your database for a few seconds. Most Redis clients are set to refresh their DNS address when they reconnect to the database, and you will not be required to perform any further action. If you encounter connectivity problems for more than a minute during maintenance, please refresh your DNS entries.
 
 ### Urgent maintenance
 
 Urgent maintenance refers to any activity that could affect service and cannot wait for scheduling. This includes applying urgent security patches.

-You typically do not need to set a maintenance window manually as Redis will attempt to perform maintenance during low-traffic hours when possible, based on the region where your subscription is located. If you want to control when Redis performs maintenance for a Flexible subscription, you can [set manual maintenance windows](#set-manual-maintenance-windows) to ensure non-urgent maintenance will occur at set times. Configuring or altering the maintenance window will not have any impact on your subscription or databases.
