Summary:
Software on the load balancers and firewalls will be updated.
Details:
To ensure this firmware update proceeds as smoothly as possible, the backup units will first be upgraded with the new firmware, after which the primary units will be updated. During this maintenance, traffic will be switched between the primary and backup units several times. These switchover events may cause one or more brief interruptions lasting one or several seconds to the services behind the firewalls and load balancers.
