No, these services are not going away for faculty, staff, and students. Those populations are fairly constant in size, and the services are used directly in support of the university's academic and research missions. Storage space currently used by alumni is not available to faculty, staff, and students. Introducing Google storage caps for alumni frees up more of this space, which is needed for mission-critical work.
We will apply a storage cap to faculty, staff, and student accounts, as well. You can learn more about those changes from CIT.
