Usage Statistics

A statistic in which the counting methods change within the periods considered has become meaningless! Therefore, unfortunately, the previous form of the statistic cannot continue. The old data is still available in the archive but it is no longer comparable with the new data.

For example, if the same IP dialed into the homepage at two different times, this was counted as two visits. The required interval between recognizing a single visit and two visits was 30 minutes. (The assignment of an IP to a user could have changed during this time). The new server operating system counts this process as one visitor only.

However, this homepage is widely used in many internal networks (intranets of universities, companies) that appear outside as a single IP. All users in these universities and companies are now only a single visitor. Although the log files on the server become larger, about 70 to 80% of the previously counted data is recorded only. Continuous statistics are therefore no longer possible.
