Microsoft Limits Advanced Notifications
According to a recent blog post, will be limiting access to its Advanced Notification Service. ANS provides customers with a heads up of the upcoming patches, which allows them to schedule changes and maintenance windows. Chris Betz wrote that Microsoft no longer make this information broadly available through a blog post and web page.
Future ANS notifications will only be available customers with premier support and members of the Microsoft Active Protections Program. Customers without access to these channels are encouraged to use TechNet myBulletins.
