 ### Zone down experience
 
-- **Zonal zone down experience**. During a zone-wide outage, Community Training can have either complete or partial service disruption. The extent to which it is available depends on various factors, such as whether the entire datacenter is down, or whether a specific dependency service isn't no longer available in that zone.

-- **Zone redundant zone down experience**. During a zone-wide outage, you won't experience any impact on provisioned resources. However, you should be prepared for a brief interruption in communication with those resources. In a zone down situation, Clients typically receive 409 error codes, as well as retry logic attempts to re-establish connections at appropriate intervals. New requests are directed to healthy nodes with zero impact on the user. During zone-wide outages, users are able to create new resources and successfully scale existing ones.

Disaster recovery is not active-active or active passive, but is instead based on recovery from the most recent available backup of Azure services.

 ### Disaster recovery in multi-region geography
 
-- In the case of regional disaster, the **control plane** is manually failed over to the paired region. You should expect some service degradation in the time before the failover completes. After the failover, only read-only operations are supported until the disaster region is back online. The service is manually failed back to the original region once it's back online and all operations resume. Recovery Point Objective (RPO) is expected to be ten minutes; Recovery Time Objective (RTO), 24 hours.

To use managed disaster recovery, you'll need to [enable disaster recovery]() during Community Training instance creation in Azure. Once you enable disaster recovery, Microsoft maintains the backup of storage and database in the paired region.

-When a Community Training health check detects an outage of any service, and in any region, Microsoft will request your consent for failover to the paired region. Microsoft will let you know which features will be available during the disaster recovery procedure. Once Microsoft receives your consent, the Community Training team can then start the disaster recovery procedure.
