This document provides insight into the period between 4 and 7 March, which saw a series of (D)DOS attacks launched against www services operated in the Czech Republic, as seen from the perspective of the CZ.NIC Association and CSIRT.CZ (the national CSIRT of the Czech Republic). Despite our great effort to collect as much information and data as possible and to continuously monitor the situation, we are aware that we do not have all the information at our disposal and that our overview may not be complete.
