I think this time GFW is trying hard to take down this VPN service in China.
In these days, I tried to connect any country, however only one or two country could be connected and others showed low bandwidth or no response error.
Connectivity was not stable all the time, few minutes or hours later, all countries could not be connected or ping-able.
It seems GFW is keeping learning to block the VPN connection.
Once we connected successfully, it would be blocked in the future.
And of course, we need explanation about this block event.
There's no further update and ETA, that's annoying us.
