I think that you need to run the command "termux-setup-storage" to be able to r/w again:

I've just tested the nameservers again and ICANN ones seem to be a lot faster than before. OpenNIC ones are down for me right now.

I've tried using the DNS listed in the page and they were very slow resolving new names (I'm in Spain).

DNS Benchmark (https://www.grc.com/dns/benchmark.htm) shows this results: https://ghostbin.com/paste/rr65w

Are they normal? Or are they slow because the servers are located in the US?
