Just seen this on BBC news.
Yes that seems to be what's happened.
Though as the story said these blocks are easy to get around. VPN are advertised a lot these days, and also there seems to be browser addons that are out there as well.

I mean imagine how much money they would make if they offered films, tv shows etc, not region locked, 1 or 2 months after release.
