Bill has mentioned that he updates the ws.surbl.org data every 15 minutes.
how often/hour is this data loaded into the ws.surbl.org zone?
I grab Bill's data three times and hour. I can make that more frequent if we deem it useful.
Generally I like to sample events at about 2.5 times their characteristic frequency (Nyquist Theorem), which would suggest a 6 minute sampling rate if Bill's data can change in 15 minutes. Since we're using rsync it should not cause too much load.
What does anyone think of this?
