I would like you to improve Service Health alert notification for specification changes (Planned maintenance),
and to guide me in a way that users will notice by some means.

<detail of request>
・information on changes to specifications has been communicated more than three months prior to the date of change.
・If I cannot follow the information from the history, please inform us again just before the specification change. (Currently, If the alert emails were sent before creating a target resource which will be planed maintenance ,
it could not receive the email which notice about planed maintenance.)
