I didn't think of that.

While there is noise on my graphs that is almost certainly due to the network, there is definitely a correlation between ambient temperature and the slope of the graph, with a distinct 24 hour cycle most of the time (admittedly network traffic could also have this pattern), which probably accounts for something like half of my +-2 ms.
