You must respond to the annual renewal request email for each domain within three weeks or your site will be locked and then removed two weeks later.

After leaving Stanford (i.e, graduated, retired), you have an option to transfer your website to a paid account with Reclaimhosting for a small fee each year, or to another third-party service provider. You have a three-month grace period after graduating or retiring from Stanford before your website is deleted from su.domains.
