It would be better to monitor the time taken to answer a DNS query.
A machine may be able to respond quickly to pings, but still take a long
time to respond to a DNS query.

I agree that QoS is a better way to regulate the connectivity of the DNA
than link size. If a 2LD is only small, why should it be necessary to run a
512k connection when a 64k link would offer the same quality of service?


Section 4 could become:

4. Must have permanent connection to the Internet maintained such that the
DNA's name server can respond to DNS queries from munnari.oz.au with a
packet return time not exceeding 300 milliseconds.
