It was what I was fearing of… 2/3 days ago the SEA-ME-WE4 (submarine cable) link went down. And I found that I couldn’t reach the sites which were hosted in local webservers (eg. btcl.gov.bd). I really don’t have a good concept of how these routing take place, but I think it is because of the Root DNS resolving Zone not being present in Bangladesh. To reach this root zone the International connectivity is a must (Submarine Cable). As far as I know- A company has been awarded the international gateway under their operation, if they can have a local DNS root zone which will look for if the requested URL is located at a local server. Since all the ISPs will connect through the same gateway, any web server hosted locally using local ISP’s bandwidth, will be available to users of other ISPs, thus not requiring Submarine cable bandwidth for these locally hosted sites. This will also encourage people to host websites at locally hosted servers, specially the sites which has most of its users from Bangladesh.
Expert’s words in this topic are welcome and will be encouraged….
