Summary:
 
On Wednesday April 28th between 00:00 hrs and 04:00 hrs we will perform maintenance on our load balancers and firewall cluster. During this maintenance we will apply a software update.
 
Details:
 
To perform the update as smooth as possible the backup units will be updated first, followed by the other unit. During this maintenance, we will switch between the active and backup units a number of times. This switchover can cause one or more short disruptions of one or a few seconds to all load balanced and firewalled services.
