What .EU domain status can I see in my administration and what does this mean?

You can see these sorts (domain status) of your domain .EU in your customer administration:

1. Registered - the domain was successfully registered, the registration confirmation was sent to the contact email.
 
2. Quarantine - the domain has not been prolonged in time, and after expiration it has reached the status of Quarantine, from which the domain can be removed for a standard extension fee. The quarantined domain is inactive for 40 days, after which is completely released to a new registration.
