I'm not sure what change you're suggesting. The relevant page of the Royal Gazette (cited by P Chan on this mailing list[1], and attached) says Sierra Leone switched on July 1, not June 1. If there's some evidence the actual change was in June, please let us know. [1] https://mm.icann.org/pipermail/tz/2020-December/029619.html
