I don't know of any implementations that keep prefixes in a persistent
store. My expectaction would be that when the host is turned back on in
September, it will send an RS and get RAs and auto-configure itself without
any memory of the old prefix.
Furthermore, I think the site administrator has screwed up by advertising a
two month lifetime and then trying to remove the prefix in one month.
