The .eu registry has a maintenance window starting from Friday 12 September 22:00 UTC to Monday 15 September 07:00 UTC. During the maintenance it is not possible to register, update or delete domains. The reason for the maintenance is a switch to a new registration platform. During the maintenance we also can not register, update or delete domains via the .eu portal.
We recommend to register domains and update contact information in time (when needed) before the maintenance starts. We also recommend to not change the nameservers after Thursday to prevent any downtime. The reason for this advice is when you change the nameservers and the configuration is incorrect we can not correct it for you until the maintenance has finished.
