Our Advance Notification Service (ANS) was created more than a decade ago as part of Update Tuesday to broadly communicate in advance, about the security updates being released for Microsoft products and services each month. Over the years, technology environments and customer needs have evolved, prompting us to evaluate our existing information and distribution channels. This desire to improve is why customers may have seen us introduce myBulletins to provide bulletin reports tailored to customer preferences, discontinue the Deployment Priority matrix in favor of the Exploitability Index, modify the Exploitability Index to account for more threat scenarios, simplify security bulletin content to help customer understanding, and create a centralized glossary for bulletin definitions. The change being announced today fits within that context.
We are making changes to how we distribute ANS to customers. Moving forward, we will provide ANS information directly to Premier customers and current organizations involved in our security programs, and will no longer make this information broadly available through a blog post and web page.
