I have not noticed the issue in Carmel. I was actually running tcpdump overnight and continued to see at least incoming traffic. I even received some SPAM at 06:09.
What DNS servers are you using? If you like, you can try using Google's DNS servers: 188.8.131.52 and 184.108.40.206 (2001:4860:4860::8888 and 2001:4860:4860::8844 if you have setup IPv6). Personally, I run my own DNS server that caches directly from the root servers.
