Does anyone mind if we try this out and see what effect it has on traffic?

Go for it!

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.
