I am not worried so much about the root servers here because of the reasons you cite. The root server system is engineered to cope with hugely excessive loads already. I am worried about all the other root servers that have to deal with much lesser query loads and might feel the impact of lowered TTLs much more. > ... and the impact of > having it in many TLD's will be to put downward pressure on TTL's. this > all needs to be looked at very carefully. Yes, we need to keep an eye on this and argue against lowering TTLs across the board for little good reasion.
