Packet Clearing House Report on Root Nameserver Locations
This map plots the density distribution of the root nameservers which are the top of the Internet's domain-name resolution hierarchy, by country. Countries must have root nameservers, country-code top-level domain (ccTLD) nameservers, and Internet exchange points (IXPs) within their borders in order to maintain autonomy and internal connectivity during periods when international cables are damaged.
Hold your cursor over a dot on the map to see the city name and which root-servers are present there. We use the United Nations list of countries, and countries which display as less than one pixel are listed below, but aren't indicated on the map.
