[Bug 1494519] [NEW] general network slowing after update

[takdag]

Public bug reported:

after I updated several ubuntu 14.04 machines I have experienced slow
network speeds, stalling and hanging up. For example I can only
sometimes SSH to these machines, and when I do it freezes because of a
lost connection. I changed the MAC address on one of these machines and
the problems seem to have went away but they returned at a later time. I
noticed in the update log that bind9 was updated.
