Description of changes:

PRODUCTION:
As a prerequisite for the upcoming future Hub upgrade, the audit database machines must be archived beginning 8/28 at 5:00 pm EDT.

Impact:We do not anticipate any production service outage; however, the Hub Production Dashboard will be delayed for an estimated 3 hours, catching up once the archiving is complete.

VALIDATION:
The Hub Validation environment will be upgraded beginning 8/30 at 12:00 pm EDT.

Impact:
This will be a rolling upgrade to the application layer on server instances that are in a scale-out configuration, and therefore we do not anticipate any service outage.  However, the Hub Validation Dashboard may queue messages at times to be propagated once the upgrade process is completed.

Scope:
These changes will be applied to the eHealth Exchange Hub PRODUCTION and VALIDATION environments as outlined above.

Support:
eHealth Exchange staff will monitor administrator@ehealthexchange.org for 30 minutes after each maintenance window is completed. 

ADDITIONAL INFORMATION AND REMINDERS:

The eHealth Exchange Hub team has implemented a recurring weekly scheduled maintenance window each Thursday evening at 5:00pm ET for all non-urgent events.  The duration of each maintenance event will be determined by the respective changes for each event, and details will be communicated out to all Participants at least 48 hours prior to the event.  If there are no changes for any given week then the maintenance event will not occur and no notice will be sent. Also please note that Operating System and similar updates that do not require a service outage, and do not require changes to the application layer, will be performed during this scheduled maintenance window without specific notice due to their frequent and routine nature.
