Right. Although our service provider seems to have a quite robust connection, the bottle neck is of course our rack's uplink.

I suspect (after ruling out having a warez distro site on the box) the latter. Our uplink provider monitors traffic for us and the spikes are there - it's not that our uplink switch just stops working (as it would if too many packets per second came in), the traffic really is there. So my wild guess was that we were just ping -f'ed, stacheldrahted or something like that.
