In the night between Sunday and Monday our primary DNS servers receive strikingly more queries than normal that indicated that our DNS servers were subject to amplified DDoS attacks. Yesterday afternoon attack was intensified, and our network were congested and at moments were not able to transfer the traffic. Past evening we have reconfigured our network and routing, and added blocking devices in front of the systems in order to reduce load and return system to fully operational state. The attack is still going on and we are closely monitoring the situation.
