Root server instance and DDoS attacks

Maldives suffers from DDoS attacks from time to time. The attack traffic is coming from overseas and therefore the international links are saturated.  However, the local backbone within the country should have sufficient capacity to serve local access but due to the need to do name query with root zone nameservers which are in overseas, local people can not access local website.  The solution is of course to implement anycast root server instance within the country.   Apart from mitigating the effect of DDoS attack, the other purpose is that if there is a break in submarine cables due to earthquake, at least, local content can still be accessible by local people.
