Bandwidth about US$100 per day (assuming 40 megabits/s at US$80 per megabit/second average over a month) Rack space about US$60 per day. Two racks at US$900 each. Total for rack space and bandwidth would be US$0.11 per minute. During that minute the servers would deliver 640 requests per second, or about 60 requests per cent of recurring costs. 640 is the average requests per second for the last 12 days. We've spent more than US$80,000 on hardware this year (about 78,000 from the main vendor in 10 months including the most recent order). Counting the main vendor only that's US$266 per day in hardware. As long as traffic continues to rise we'll need to keep buying more hardware to keep up. Hard to say when it will stop rising. Total to handle being around the 200th most visited English language site according to Alexa is over US$436 per day or US$0.30 per minute. About 21 requests per cent including capital costs but that's misleading long term because eventually we will stop needing to buy so much hardware.
