Ban waves have been introduced to detect perpetrators, servers now take on less than three matches each, punishment for quitting too many matches – a side-effect of players caught in an attack, known as the escalating abandon sanction – has been disabled, and there’s heightened network traffic monitoring. In a report from Ubisoft, DoS/DDoS attacks are down 93% since many of the precautions outlined were taken.
Taking a number of measures, including having less matches on each server and monitoring network traffic, has yielded considerable results, making the shooter much more stable. There’s been a massive decrease in the amount of server hacks on Rainbow Six Siege since Ubisoft initiated a strategy to combat denial-of-services and distributed denial-of-service (DoS/DDoS) attacks.
