From 31 August 2017 (20:00) – to September 2, 2017, the planned Maintenance of the SK-NIC registration system will be scheduled. The Maintenance is related to the complete transfer of the old system to a new one. During a downtime, the system will be completely unavailable and no service for the .SK domain (registration, renewal, re-registration, etc.) can be ordered.
Extend your .SK domain in time, preferably until August 30, 2017 to avoid a domain shut down!
