Some customers have reported experiencing Comcast throttling with a VPN. While it’s unlikely that Comcast is throttling their connections because of a VPN, it can still throttle their bandwidth during peak hours between 7 P.M. and 11 P.M. on weekdays. In general, a VPN can help improve your internet speed if you’re experiencing content-based throttling. This is when your ISP slows down your connection if you’re accessing a particular app or website. CyberGhost’s military-grade encryption can help mask your online activity, which blocks your ISP from seeing what you’re doing online so it won’t throttle your connection.
