Sky Broadband has apologised to its customers who have been inconvenienced by a PlayStation Network-related glitch, Eurogamer reports.
According to the ISP, the problem has prevented people from accessing and using the PlayStation Network from between 17:00 BST and midnight.
However, the issue is confined to Sky Broadband Connect customers using peer-to-peer applications, with Sky pointing out that the malfunction has not had an effect on other Sky Broadband users as there are no traffic management policies operational for on-network broadband services.
"Our network management system mistakenly classified PlayStation 3 traffic in a way which meant some customers using their consoles to access the internet may have had their speeds reduced, in line with our network management policy for Sky Broadband Connect," Sky explained in a statement released to the news provider.
Sky says it is now working on rectifying the error as a matter of priority.
Sky Broadband recently announced a revamp of its product range, with customers on its higher-end deals securing a faster broadband connection.
