In all cases the delegation is messed. My guess is that its a zone delegated incorrectly. I.e. the network administrator hasn't bothered to let his DNS upstream know about his server. > Is this average time? Got a distribution? This is the average time. A distribution, queries on the Y axis, seconds on the X axis, of this data set: 121.0 # 116.0 # 110.9 # 105.9 # 100.8 # 95.8 # 90.7 # 85.7 # 80.7 # 75.6 # 70.6 # 65.5 # 60.5 # 55.5 ## 50.4 ## 45.4 ## 40.3 ## 35.3 ## # 30.2 ### # 25.2 ### # 20.2 ### # # 15.1 ##### # # 10.1 ###### # # 5.0 ####### # # ------------------------------------------------------------- 0 40 80 Nothing too surprising here. > Were queries sent with RD?
