Usage Statistics

Statistics in which the counting methods change within the periods under consideration have become meaningless! For this reason, the previous form of statistics cannot be continued. The old data can still be retrieved in the archive, but cannot be compared with the new data.

For example, earlier, when the same IP dialed into the homepage at two different times, this was counted as two visits. The necessary 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). In the new server operating system, this process is only counted as one visitor.

However, this homepage is used in many internal networks (universities, companies) as a reference book, which appears to the outside as a single IP. These universities and companies are now only a single visitor. Although the log files have become the same size in terms of volume and some cases even larger, only about 60 to 70% of the previously counted data is still recorded. A continuous statistic is therefore no longer possible. This new internal counting method has been adapted to the external counting method of services such as Alexa, which can no longer register visitor traffic if the pixel, script or byte to be counted is already stored in the user's cache. Anyone interested in this new counting method can now calculate for themselves.

A summary as visitors per year is not possible this year. In the following table only the current monthly values are mentioned:
