Description

Impact:

 

Long-lived connections (e.g. SMPP) will be broken and must be re-established and short-lived connections (e.g. HTTP) and potential MPLS connectivity may be unable to be established for a few (1-2) seconds, when control of the LTM cluster transitions between the nodes.  Most SMPP binds should be down only as long as it takes for the client to recognize the connection is broken.

At the very end, I am expecting the SMPP binds will be restarted to ensure all are re-established cleanly, but that operation will be performed by the team supporting those application.

 

Duration:

    There will be three changes of control during this maintenance, each with an expected downtime of no more than a few seconds.
