- 2014-11-17: dblp usage statistics
We often receive questions like "How many users are using dblp?" or "How many hits do you get per day?" While we do not have a live statistic for these questions like the one we have for our data stock (yet) we can of course share the usage statistics we learn from our web server's log files.
There are three "official" dblp servers which are updated and synchronized on a daily basis:
- server Trier 1: http://informatik.uni-trier.de/~ley/db
- server Trier 2: http://dblp.uni-trier.de/
- server Dagstuhl: http://dblp.dagstuhl.de/
These servers do show a very different rate of usage, with Trier 1 being the by far most widely known URL. This is of course due to the fact that server Trier 1 is ranked so highly by Google. Server Trier 1 is currently still hosting the old dblp web system, while servers Trier 2 and Dagstuhl are already hosting a beta version of the brand new web system. (A full update to the new web system is scheduled for early 2015.)
The following figures have been collected during October 2014. These figures ignore the traffic caused by known bots and crawlers.
