The name servers records turn a floating domain into a fully functional host by anchoring it to a certain server on the web.
Since the availability of a web server might at times be compromised, most domain names have two name servers – the main one (NS1) and a backup server (NS2), which takes over if the first one is experiencing problems.
To further secure your online presence, we’ve also added a second (NS3) and a third (NS4) backup name server to each host.
Geographical location-based name server backup service
We’ve learned from experience that the use of different networks to handle name resolution within one and the same data center is not a solid guarantee for online availability. This is why we’ve implemented backup name servers in three different locations around the globe – NS2 in the Chicago data center (already existing), NS3 in the UK data center and NS4 in the Finnish data center. This way, in the event of a massive network disruption in the Chicago data center, each next-level backup server will be able to take over the job from the previous one in the chain.
A backup name server (NS3) in the UK data center
While implementing the location-based backup service, our admins first added a name server in the Pulsant data center in Maindenhead, UK. The UK facility has direct connections to international backbones and a very secure infrastructure. Also, the UK is a country with a lower risk of natural disasters like tsunamis and hurricanes, as compared to the USA.
A backup name server (NS4) in the Finnish data center
We’ve selected the data center in Finland to house the fourth name server for a reason. Located in an underground compound, which used to accommodate the Finnish Defence Forces, the data center can withstand even an atomic bomb attack.
Apart from the natural protection against disasters of all sorts, the facility offers an iron-clad security system, which further guarantees the flawless performance of the sites hosted there.
