Changes this week, as of Saturday 04:00 hrs GMT.
Added to the list Bhutan, Timor-Leste, Mongolia, Aruba, Samoa, Kiribati, Micronesia, Tonga, Vanuata, and the Solomon Islands (clearly they haven't run out of obscure options which are near impossible to get to, yet).
Removed from the list: Estonia and Latvia. You will now need to self isolate from these countries.
Modified: Denmark is no longer extra-restricted off the mink issue, but it's still not a travel corridor country, self isolation applies.
