For example, if a country disappears due to a natural disaster (earthquake, volcanic eruption, tsunami...) or war, will the domain be managed by ICANN?
As an extreme example, if Palestine is wiped off the face of the earth by war, what happens to the .ps domain?
Like most things ICANN there is a working group for it <a href="https://ccnso.icann.org/en/workinggroups/pdp-retirement.htm" rel="nofollow noreferrer">https://ccnso.icann.org/en/workinggroups/pdp-retirement.htm</a><p>In practice though there are tons of politics involved and something like .su is supposed to be sunset but everyone is really careful not to mention .io Realistically I'm not sure there will ever be a consensus around what this. Too many diverging opinions.
