It's not uncommon (although I would agree it is ill advised) practice for some
web sites that think they cater only to an audience in a particular geography
to block access outside of that geography. I ran across this when my credit
union would not let me connect to their web server from S. Korea.

However, I took it up with the credit union rather than NANOG. Is there a
reason you bring this up here instead of with the SSA?
