At Libcom.de we have decades of experience with the Domain Name System (DNS). For every service you operate, DNS is the backbone. If the DNS service you operate on fails, your servies will also fail.
We offer Domainhosting running on the concept of a hidden master. This means the host in control is not directly accessiable from the internet. This gives an extra layer of security.
ns0 and ns2 are about 400kms apart so even bigger incidents will not bring down our system. Even in an event of a failure we have fast and bulletproof disaster recovery plans. There's a builtin backup concept, using encryption and different sites.
At Libcom.de we also operate High Performance DNS Load Balancers. Special features like split horizon or super fast caches are possible.
