It's not 'everywhere' around the world...BBC Canada hasn't even aired the Patagonia special yet. They won't be airing Series 22 until after they've aired that (part one is Jan 31st). We might get series 22 in mid February (it's not listed as airing within the next two weeks, at least).
Probably delayed so they can edit out the great music and some content for commercial time. Sad, really.
