Youtube links pull in odd information, and no thumbnails.

Until a few days ago I was posting youtube links, and the thumbnail and link description would be filled in automatically.

Now, there's no thumbnail image and instead of the youtube preview text for my linked video, its some generic youtube stuff in french:

• YouTube www.youtube.com Profitez des vidéos et de la musique que vous aimez, mettez en ligne des contenus originaux, et partagez-les avec vos amis, vos proches et le monde entier.

Something broke?
