EURid, the Registry for .eu domain names, has issued a communication as a result of the announced delay to Brexit. They have said that the plan set out and published in March 2018 here, impacting .eu Registrants from the UK and Gibraltar, has been postponed.
EURid will communicate the next plan of action as soon as there are official updates from the European Commission on how to proceed.
To read the full announcement see https://eurid.eu/en/register-a-eu-domain/brexit-notice/
We will continue to work with you to transition your names to EU entities as this will still be required post-Brexit.
