Secondary DNS, Secondary MX

Basic information

Secondary DNS – In case of one server failure, there is still the second one which starts working fluently and automatically in full instead of the primary one
Secondary MX - In case that it is impossible to contact either of the postal servers, the sender gets an email with error report. With Greenhousing servers this can be prevented by ordering secondary MX.

More information

Secondary DNS
DNS (Domain Name System) is a service of domain names translation into IP addresses. In case of primary DNS server failure, for the standard internet user it means the same as switching off the whole internet (in case of client DNS server). That is why there is an offer of keeping records of two independent DNS servers. In case of the failure of one of them, the second takes fluently and automatically its all its work. It is important to mention the fact that our secondary DNS server is placed absolutely separate, logically on the network and also physically in a different server base that the primary one.

Secondary MX
This record simply gives the address of postal server, where are based email boxes for the iven domain. There are usually at least 2 of them and they show the record of ALIAS (CNAME) type, i.e. letter name, not numerical IP address. In case none of the postal servers respond, the sender gets an email with error report.
With Greenhousing servers this can be prevented by ordering secondary MX.
In case of the failure of one of them, the second takes fluently and automatically its all its work.
