Data point: out of 40,000 random DNS requests logged on my work station
over the last year, 20% underwent at least one retransmission, resulting in
service times larger than 2 seconds. The average packet loss rate on the
regular IP service only explain about half of these retransmissions, which
makes me suspect that a lot of additional losses are caused by congested
DNS servers. Increasing our reliance on the DNS is definitely not a good idea.
