I have a similar graph of traffic size here, 500bps/month for the median of one-minute samples. 1100 bps/month for the average. > If I read your bandwidth numbers correctly, you're serving roughly > 3,500,000 requests / day? Back then I saw about 1,500,000 requests / day. 150,000,000 requests for 135 days. 1,100,000 requests per day on average. Looking at the last graph on page 21, there are days with almost three times the average, so you are right 3.5 mil seems about right. > You also have some interesting details about the odd behaviour of various > systems' IP implementations.

I have one hypothesis: a TTL of 129-173 is weird because it's > quite high, and yet also very low if the system sets TTL to 256.
