On December 25, 2014, PlayStation Network and Xbox Live suffered network disruption after a denial-of-service attack.[13] Both services were flooded with millions of inauthentic connection requests, making it hard for genuine users to establish a connection. Functionality was restored on December 26, with some users experiencing difficulties in the days that followed.[14] On January 1, 2015, Sony announced that users would be compensated for the downtime with a 5-day extension to PlayStation Plus memberships.[15]
