Hi-Rez Studios is an independent developer and publisher of free-to-play video games, with millions of players located across the Americas, Europe, Asia and Africa. If Hi-Rez is unable to deliver a high-quality experience to their players, they risk frustrating their passionate user base and losing gamers to their competitors. Maintaining high network performance is crucial to Hi-Rez's success. Hi-Rez handles about three DDoS attacks per day, each more than 70 Gbps. Given the volume and frequency of attacks, they made the decision to always keep their network behind Prolexic, their DDoS mitigation provider. With ThousandEyes in place, Hi-Rez can see not only into their own network, but also into the changes and issues occurring in their upstream ISPs and other service providers. Now, the Hi-Rez team can understand whether users are able to reach their network during a DDoS attack and locate the failure points that need reinforcement.
