The TLD was formerly administered by Planet Three Limited, a company with offices in the United Kingdom and Australia, which went bankrupt and ceased operations, voluntarily transferring management to CIIA (called Dot CX Limited at the time).[citation needed] The local (shire) government of Christmas Island endorsed the transfer, but the Commonwealth of Australia (which has international authority over Christmas Island as an external territory) did not immediately approve it. Australia has since published a Memorandum of Understanding which recognizes CIIA as the legitimate manager of .cx.[citation needed]

It is unclear whether the Christmas Island Domain Administration is currently operating. As of February 2021, the URL listed in its IANA record, as well as the Network Information Center nic.cx, do not have associated websites.[1]

The domain achieved a certain degree of notoriety when it was used for the shock site goatse.cx, to the point the CIIA was forced to take down the website following complaints by Christmas Islanders.[2]
