OK I'm changing the TTLs on all tue SURBL lists to 25 minutes
which is a midway point between the 20 minutes I was going
to try for SC and the 30 minutes we proposed for the rest of
the lists. 25 minutes is also a good sampling frequency
to capture data that has a 1 hour characteristic frequency.
This is mainly an experiment to see what effect it has on
DNS traffic. If the traffic on SC is not a lot lower, I'll
change it back to 10 minutes. If the traffic on the other
lists is not a lot higher, I'll leave it at 25 minutes.
