Winter arrived for subscribers of DirecTV Now for just a moment, says Comicbook.com.
Subscribers received a notification that the Game of Thrones Season Eight premiere had been uploaded.
Fans took to social media to share the fact that they were taking full advantage of the leak.
It's not clear whether the "leak" was a mistake on the part of DirecTV or was part of guerilla marketing efforts.
With how secretive HBO has been about the show's finale season, it's likely a mistake on the part of DirecTV.
Nothing is for sure in the age of digital media and viral marketing, though.
The episode was quickly pulled off although it's possible enough people caught it to spread spoilers.
Game of Thrones airs Sunday nights at 9/8 p.m. Central on HBO.
