Spectrum often throttles the VPN traffic, and Spectrum clients find the VPN inactive. When we analyzed further to check the claim’s authenticity, we figured out that Spectrum throttles VPNs and uses few tools to detect the presence of VPN.
But this won’t be an issue if you use a VPN with obfuscated servers. Connecting with these servers ensures that VPN-protected traffic doesn’t look suspicious and makes it look like any regular HTTPS traffic. This way, obfuscation capabilities will ensure that Spectrum cannot throttle VPNs.
