Interesting to see that the .HT top level domain continues to function despite the devastation to the country’s telecommunications infrastructure. This is because .HT has six name servers, 4 of which are outside the country. The one in Port Au Prince, for example, is not currently working but all those overseas are.
If you are currently sat on a hillside in Haiti this isn’t likely to be much comfort. However work is underway to provide a route to the outside world via neighbouring Dominican Republic. Once this is in place then .HT based communications will then be able to restart within the country and it is to a certain extent an example of the resilience of the design of the internet.
