We do have issues where regional distribution effects access particularly to services which block VPN traffic. Our servers are spread world wide, its more of a problem with the service blocking our VPN traffic which is recognised as a proxy.
The only work around for this problem is to turn off the Internet Filter (VPN). There is no timer on this setting so you do have to remember to turn it back on.
