ICANN Announces New Continued Operations Instrument (COI) Amendment Service

15 September 2015 – ICANN today launched the Continued Operations Instrument (COI) Amendment Service. This service will provide a method for Registry Operators to request changes to the level of funding in their COI. The COIs are an important part of safeguarding the operation of top-level domains (TLDs) by ensuring sufficient financial resources to cover critical registry functions in the event of registry failure.

In December 2011, ICANN published guidance to help Registry Operators calculate the estimated costs for the operations of a TLD based on their projected domain registrations under management (DUMs). Since that time, the launch of new gTLDs has provided Registry Operators with market-driven data points on which to base their projected DUMs. With the COI Amendment Service, Registry Operators now have a mechanism to request a change to the value of their COI to align with the updated DUMs projections of a TLD.

To submit a request, Registry Operators must be in good standing and the domain must have been in General Availability/Registration for a minimum of six months. To begin the process, the registry primary contact must open a case in the GDD Portal and submit a completed COI Amendment Request Form [PDF, 1.04 MB]. For additional requirements, please refer to the Frequently Asked Questions page and the COI Amendment Service Guide [PDF, 282 KB].

ICANN is committed to ensuring that sufficient financial resources are available for the continuity of critical registry functions. Specification 8 of the Registry Agreement states Registry Operators shall have a COI that provides for sufficient financial resources to cover the five critical registry functions. Should a COI be insufficiently funded, ICANN will ask the Registry Operator to use the amendment service to update its COI within 60 days.

A webinar about the COI Amendment Service is scheduled for Wednesday, 30 September 2015 – details below.

ICANN's mission is to ensure a stable, secure and unified global Internet. To reach another person on the Internet you have to type an address into your computer - a name or a number. That address has to be unique so computers know where to find each other. ICANN coordinates these unique identifiers across the world. Without that coordination we wouldn't have one global Internet. ICANN was formed in 1998. It is a not-for-profit public-benefit corporation with participants from all over the world dedicated to keeping the Internet secure, stable and interoperable. It promotes competition and develops policy on the Internet's unique identifiers. ICANN doesn't control content on the Internet. It cannot stop spam and it doesn't deal with access to the Internet. But through its coordination role of the Internet's naming system, it does have an important impact on the expansion and evolution of the Internet. For more information please visit:

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as"""" is not an IDN."
