Microsoft Production Server Traces
Because of the size of the traces, the BuildServer traces have been repackaged by IOTTA into eight zip files. The first seven files are divided into one for each of the first seven timestamped hours in the original traces. The last file contains traces of the remaining 18 traced hours, in which the activity was much lighter. All eight zip files contain the same Readme.* and Disclaimer files. They are designed so that if all are unpacked in the same directory, the original trace collection will be recreated.
