After upgrading to the newest systemd 233-5ubuntu1 (in artful proposed) I got no network.
This is very likely a DNS issue.
As a workaround downgrading back to systemd 232-21ubuntu3 the network and DNS work fine.
So something odd has happened between these versions.
My setup is a fully upgraded artful with proposed repo turned on.
I use only Gnome DE with GDM.
Everything else works fine, but not systemd 233-5ubuntu1.
