After trying DNS TTLs at 1 hour, 25, 20, 15 and 10 minutes, it appears that 15 minute TTLs optimizes both name server traffic and the quickness of records being added or deleted from the lists. Therefore, we are standardizing on 15 minute TTLs for all SURBLs.
Note that this result applies to SURBL data and uses of it. It may or may not apply to other types of RBLs.
