Please try to monitor your network traffic if possible. At this moment it looks like we need more information where this issue comes from.
And please visit ‘Account → Edit profile’ menu to enable the Connection Log feature to see where your traffics were used. You can find it at Sign In - MUDFISH: Acceleration As a Service link.
At this moment I don’t know why because as default we’re not doing any kind of logging to trace your traffics for privacy protection. So after enabling it, you can see connection logs at ‘Status → Access Log’.
