Web server traffic in crisis conditions

In English During recent years we have seen several large-scale crises.
The 9/11 terror attacks, tsunamis, storms, floods and bombings
have all been unpredictable and caused a great deal of damage.
One common factor in these crises has been the need for
information and one important source of information is usually
web sites. In this work three new sets of web server access
logs are presented and analyzed, one of which represent the
traffic to the major news site, Aftonbladet, in Sweden after
the bombings in London, 7th of July 2005. The differences
in document popularity between the crisis logs and the other
logs are investigated.
