Description of changes:
Minor configuration changes will be applied to a subset of routers on the PRODUCTION Hub in order to support ongoing Participant Responder validation testing.

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

Impact:
We do not anticipate any service interruptions during the maintenance event.  These changes being made are to the Hub “test harness” configuration only.  Real-time routing of messages through the Hub will NOT be affected.

Support:
eHealth Exchange staff will monitor administrator@ehealthexchange.org during the maintenance window to address any questions or concerns.

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.
