The Internet Corporation for Assigned Names and Numbers (ICANN) has made a significant decision to retire the .SU domain by the year 2030. The .SU domain, a relic from the Soviet era, is currently managed by the Russian Institute for Development of Public Networks and hosts approximately 100,000 domain names. ICANN, through its oversight body Public Technical Identifiers (PTI), has initiated the retirement process by informing the domain operator of its intentions.

The retirement of the .SU domain aligns with the country code top-level domain (ccTLD) retirement policy established by the Country Code Names Supporting Organization (ccNSO) and approved by ICANN in 2022. This policy dictates that when a country or territory is no longer listed in the ISO 3166-1 standard, its corresponding country code domain must be phased out over a five-year transition period. While .SU was delisted from the ISO standard in 1992, ICANN had deferred any retirement actions pending the formulation of the formal policy by ccNSO.

ICANN’s notification to retire the .SU domain marks a significant milestone in the domain name industry. The decision, although based on established policies, comes amidst geopolitical tensions involving Russia, adding a layer of complexity to the process. Furthermore, the retirement of .SU could serve as a precedent for other country code domains facing similar circumstances.

The retirement process for the .SU domain is set to commence officially with the issuance of a Notice of Removal by ICANN. This notice will trigger a five-year countdown leading to the domain’s eventual removal by 2030, unless an extension is granted by mutual agreement between the operator and PTI. Despite the planned retirement, there remains a possibility for policy amendments that could potentially allow the .SU domain to continue, subject to ccNSO approval.

As ICANN proceeds with the retirement of the .SU domain, the domain name industry awaits further developments that may arise from this decision. The implications of this retirement extend beyond the technical aspects of domain management, touching on historical, geopolitical, and policy considerations. The fate of .SU underscores the evolving landscape of domain governance and the interconnectedness of global internet infrastructure.

In conclusion, the retirement of the .SU domain by ICANN signifies a pivotal moment in the domain name ecosystem, highlighting the intricate balance between technical protocols, geopolitical sensitivities, and policy frameworks within the digital realm. The next five years will witness the phasing out of a domain name deeply rooted in history, paving the way for new developments and potential shifts in the domain landscape.
