The mention of network saturation reminded me of a situation at an 
organization that I help where they were getting random timeouts while 
checking their email since last Friday. Of course, the first thing that 
they suspected was the IPCop firewall. I logged in remotely and saw that 
the load average was essentially nothing. Looking at the traffic graphs 
explained what was going on. There were two spikes yesterday where on 
the second one, 10Mb/s Sympatico connection must have been saturated. I 
outlined a troubleshooting procedure to isolate the computer(s) that 
were responsible for this traffic.

The solution turned out to be much simpler. We simply asked staff if 
they were doing anything unusual and apparently, a few of them were 
watching soccer via a streaming download. I wouldn't be surprised if 
they were doing HD as well. That was enough to bring the network to its 
knees.
