System update¶
Managed Load Balancer may provide new versions for purposes such as product lifecycle management, application of security patches, and addition of functions.
When we start providing a new version, we will update your Managed Load Balancer. This is called a "system update".

If there is a lot of information to be synchronized, it may not be possible to synchronize all the information. (In most cases, communication is not affected, although may be interrupted depending on the customer's system status.)
Operation of system update¶
System update period and notification method¶
When a system update is available, that will be posted in the "Notices" section.
