The past two years it has been a pretty much smoothe curve in the traffic
graph, but the past months (as soon as it started hitting 1500mbit/s) the
graph started to get rugged the way it is now. I interpret that as
trouble... It used to spike a few times a week max, nowadays it seems to
do that hourly. 

I interpret that as overload.
