The Disappearance of an Internet Domain

Today we have something a little different from Gareth Edwards, who typically chronicles the forgotten history of Silicon Valley in his column, The Crazy Ones. When the British government announced last week that it was transferring sovereignty of an island in the Indian Ocean to the country of Mauritius, Gareth immediately realized its online implications: the end of the .io domain suffix. In this piece, he explores how geopolitical changes can unexpectedly disrupt the digital world. His exploration of historical precedents—such as the fall of the Soviet Union and the breakup of Yugoslavia—offers valuable context for tech founders, users, and observers. Read this for a look at the unexpected intersection of international relations and internet infrastructure.—Kate Lee

On October 3, the British government announced that it was giving up sovereignty over a small tropical atoll in the Indian Ocean known as the Chagos Islands. The islands would be handed over to the neighboring island country of Mauritius, about 1,100 miles off the southeastern coast of Africa.

The story did not make the tech press, but perhaps it should have. The decision to transfer the islands to their new owner will result in the loss of one of the tech and gaming industry’s preferred top-level domains: .io.

Whether it’s Github.io, gaming site itch.io, or even Google I/O (which arguably kicked off the trend in 2008), .io has been a constant presence in the tech lexicon. Its popularity is sometimes explained by how it represents the abbreviation for “input/output,” or the data received and processed by any system. What’s not often acknowledged is that it’s more than a quippy domain. It’s a country code top-level domain (ccTLD) related to a nation—meaning it involves politics far beyond the digital world.

Since 1968, the UK and U.S have operated a major military base on the Chagos Islands (officially known as the British Indian Ocean Territory) , but the neighboring nation of Mauritius has always disputed British sovereignty over them. The Mauritian government has long argued that the British illegally retained control when Mauritius gained independence. It has taken over 50 years, but that dispute has finally been resolved. In return for a 99-year lease for the military base, the islands will become part of Mauritius.

Once this treaty is signed, the British Indian Ocean Territory will cease to exist. Various international bodies will update their records. In particular, the International Standard for Organization (ISO) will remove country code “IO” from its specification. The Internet Assigned Numbers Authority (IANA), which creates and delegates top-level domains, uses this specification to determine which top-level country domains should exist. Once IO is removed, the IANA will refuse to allow any new registrations with a .io domain. It will also automatically begin the process of retiring existing ones. (There is no official count of the number of extant .io domains.)

Officially, .io—and countless websites—will disappear. At a time when domains can go for millions of dollars, it’s a shocking reminder that there are forces outside of the internet that still affect our digital lives.
