I have been having somewhat sketchy network problems since upgrading to Snow Leopard the biggest one is that large updates to Time Machine fail with a network error. So I have been doing some digging and I noticed on my stats at OpenDNS that since installing Snow Leopard the requests to time.apple.com have gone from 175/day (already more than necessary) to 1745/day. Also the requests made by OpenDNS updater to myip.dnsomatic.com have gone from 36/day to 1462/day. Has anyone else noticed these sorts of problems? Clearly there must be something wrong within Snow Leopard to cause this.
