DNS Administrator

For some years now, both public and private actors have been seeing certain Internet services become inaccessible on account of problems linked to their DNS hosting. These breakdowns have considerable consequences: clients unable to access their bank accounts, online stores inaccessible, public services closed, etc. The robustness of DNS services generally suggests that Internet services are functioning normally; so, without a suitable DNS administration, an organisation can become extremely vulnerable. It is essential for any organisation to have skilled administration that allows it to maintain a comprehensive, high-quality DNS service, whether it is hosted in-house or entrusted to a hosting service provider.
