We store the current half-month that you are in and the previous three half-months. For example, if it is now the 5th June you will have the second half of April, all of May, and the first 5 days of June. At the beginning and in the middle of each month the oldest half-month is deleted.

The access log files are stored in your 'logs' directory in the following format:

The current log – access_log
The previous half-month – access_log.1.gz
The half-month before – access_log.2.gz
The half-month before that - access_log.3.gz

The oldest 3 log files are compressed as .gz files. These must be extracted before they can be read.
