The outages affected many of the government’s web sites and lasted for over seven hours.
And the cyber attackers – whoever they are – also used a distributed denial of service (DDoS) attack to take down a satirical website called GeenStijl.nl.
No one has yet claimed responsibility for the attack.
According to Reuters, phone systems and emergency channels stayed online.
The government information service said it is inestigating the attack along with the Dutch National Centre for Cyber Security.
The attackers targeted the hosting company that services the government sites – Prolocation.
