The full name of the country is "United Kingdom of Great Britain and Northern Ireland" - calling it "Great Britain" is just wrong (it excludes Northern Ireland and all other smaller islands). You would also hope an official website can get it correct.
Although entire languages get it wrong - in German the UK is translated as "Großbritannien". Edit: they do have translation for UK ("Vereinigtes Königreich") but I've never heard it said/written yet... I think I'll start using it.
A worse version is when "England" is used to refer to the UK. It's very common, maybe less so in official contexts.
