Yes. I've discussed this with Evan Dandrea a few times in the past, the
right way to fix this is by enabling connectivity checking in
NetworkManager itself, which can be done with a simple configuration
file change in /etc/NetworkManager/NetworkManager.conf (see manual for
NetworkManager).

The idea is to point it to a file under start.ubuntu.com which can be
polled regularly by NM when connected (every five minutes by default,
but this is configurable).

In the past, there has been some pushback on enabling this due to
privacy concerns and concerns that the connectivity checking wasn't
configurable/reliable enough. It will need to be investigated again, and
discussed again on ubuntu-devel@ or somewhere else suitable for broader
discussion.

I'm not planning on touching this again in the very near future, so
unassigning -- please, anyone want to shepherd this to be completed,
feel free to assign it to yourself and start up the dicussion again to
see if we can enable connectivity checking. This may be useful for
Ubuntu Touch as well.

Title:
  Constant dns traffic for daisy.ubuntu.com

Bug description:
  Watching GNetworkMonitor's network-changed signal causes constant DNS
  traffic.

  Andy Whitcroft points out that the NETLINK_ROUTE socket set up by
  GNetworkMonitor will fire events every time an ARP entry appears or
  disappears.

  Unfortunately, we currently need an additional layer of connectivity
  checking because checking NetworkManager's state for CONNECTED_GLOBAL
  is not enough to know whether we're really online. Ubuntu does not yet
  use the NetworkManager connectivity check [1].

  The likely solution to this bug is a replacement for GNetworkMonitor
  in whoopsie.

  Original report follows:

  Every few seconds, I see a dns query for daisy.ubuntu.com. After
  removing whoopsie, the traffic goes away.
