Scheduled Service Change: Test Sunone Directory Server Upgrade
The directory service uses DNS round robin, so it's possible that some users will not see an outage, even while one of the servers is being upgraded. At most, a user would see an outage up to one hour.
There is no workaround for this issue
We will be upgrading the test SunOne enterprise directory service (LDAP) during September. The test infrastructure is comprised of three servers; each will be upgraded at a separate time, resulting in a service outage of approximately one hour for each server while it's being upgraded.
