Continued Network outage starting March 17th

There have been nightly outages starting at 12:00am and lasting anywhere from 4 to 8 hours.  Support has no information about the outages until after the outages end.  They can not tell me if there will be more or how long.  I just have to wait until the outage starts.  Being that I work a night shift from 11:00pm until 7:00am this has been very disruptive.  I can not understand why the two divisions can not work together.  Everything seems to be a big secret within Cox.
