پاسخ : رفع مشکل Check Nameserver در cPanel
توضیح انگلیسی:
Selecting Secondary Servers
When selecting secondary servers, attention should be given to the
various likely failure modes. Servers should be placed so that it is
likely that at least one server will be available to all significant
parts of the Internet, for any likely failure.
Consequently, placing all servers at the local site, while easy to
arrange, and easy to manage, is not a good policy. Should a single
link fail, or there be a site, or perhaps even building, or room,
power failure, such a configuration can lead to all servers being
disconnected from the Internet.
Secondary servers must be placed at both topologically and
geographically dispersed locations on the Internet, to minimise the
likelihood of a single failure disabling all of them.
That is, secondary servers should be at geographically distant
locations, so it is unlikely that events like power loss, etc, will
disrupt all of them simultaneously. They should also be connected to
the net via quite diverse paths. This means that the failure of any
one link, or of routing within some segment of the network (such as a
service provider) will not make all of the servers unreachable.

اگر منظورتون زیرساخت های مورد نیاز هست، کلاستر کردن دو سرور هست. یعنی یک سرور دیگه بگیرید و کلاسترینگ راه اندازی کنید. هر نیم سرور به یک دونه از سرور ها اشاره کنه تا اگر یکی مشکل دار شد یکی دیگه به ریکوئست ها پاسخ بده.
در سطح کاری فعلی هاستینگ های ایرانی، واقعا موضوع مهمی نیست.
با احترام.
