According to the blog post, the admings of those organizations were also notified a year ago minus a few weeks:

> We will contact impacted institutions directly in the coming weeks to discuss a range of options for getting the storage they need

Given the quota model, it doesn't seem like notifying individual users would have made sense. It doesn't sound like the original poster would have been a domain admin.

Probably when the organization's admin does so. There are many institutions that allow alumnus to keep the Education account. With this change, they have to hastily notify the alumnus that this will no longer be honored, and they should move whatever important out of it before the account gets deleted.
