The British government announced on October 3 that it would give up sovereignty over the Chagos Islands (British Indian Ocean Territory), an archipelago in the middle of the Indian Ocean, and hand it over to Mauritius, an archipelago country in the Indian Ocean. . Although this appears to be just a political incident on the surface, it is worth noting that this territorial transfer may be accompanied by the disappearance of the popular top-level domain (TLD) ".io" in the technology and gaming industries. .

The country (or region) represented behind it It is the Chagos Islands.

By removing "IO", IANA will also reject any new ".io" domain name registrations in accordance with its specifications and begin to revoke existing related domain names.In layman's terms, the ".io" domain name and all related websites may disappear. However, it is worth mentioning that IANA may also make an exception to allow ".io" to continue to exist, because under the ".io" domain name, accompanied by a large number of companies in the technology and gaming fields, the large amount of capital behind it may be able to force IANA to make concessions .
