For this study, we limited ourselves to a web server log from a commercial web server in February, 2001. The log contained 18 hours of requests that were globally diverse containing 402,955 requests making up 3.69 Gigabytes. There were requests from 791 different autonomous systems. The top 50 AS's accounted for 232,991 requests and 2.19 Gb. To avoid complex error scenarios, we filtered out all of the requests except HTTP GET requests with successful result codes 200 to 203.
