Where I used to work we had an NTL:telewest business broadband line. We used
several different monitoring systems to monitor our customers systems [I
suspect most of our customers traffic was us monitoring them, but never
mind], one of which was Smokeping [oss.oetiker.ch/smokeping/]. This is a
great little bit of software that pings whatever you want to monitor and
then plots a graph of the latency and packet loss vs time. One thing I
noticed on the graph for every host on the internet we monitor, every day
at 1800, the latency showed a marked increase, and the drop off after 0000
was equally marked. This cannot have been an accident, so VM must be doing
something on their network for these six hours that causes an increase in
latency, even for their business broadband customers. The thing that
brought it home to me was that one day before 1800, our cable broadband
went off and the firewall failed traffic over to a backup DSL circuit. The
graphs for that night didn't show the increase in latency between
1800-0000.
