Well once upon a day I had to notice that I can not upload updates
for my website (which is at http://www.elstel.org
<http://www.elstel.org/>). I noticed that it was not possible to
ping my webserver, to traceroute it or view web pages via http on
it; i.e. the server seemed to be down.
It is not that uncommon for some services to block VPN and public
forwarding services, A number of the companies I have worked with have
this as a policy. It may not really help that much, but it have made it
in some admins standard toolbox.
As others have said geofencing is quite unreliable, I am in the US and I
never show as in the area I live in at least a few hundred miles away,
and this is going to be even less reliable as time goes on with
companies and countries starting to lease/sell IPv4 space, poorly
documented and geofencing services not updating as this happens.
