The frequency and impact of these attacks escalated significantly after Russia invaded Ukraine on February 24. However, the effectiveness of these attacks largely depended on whether targeted organizations had organized DDoS defenses. This issue was quickly remedied for unprotected organizations as global DDoS defense companies stepped in to help Ukrainian organizations that needed it.
By April, the frequency of DDoS attacks directed toward networks located in Ukraine leveled off, followed by an additional rapid decrease. This likely is attributable to Ukrainian internet properties migrating to countries such as Ireland as instability in the intra-Ukraine internet forced many network segments to rely on connectivity in other countries.
