Ligatures missing in Google Fonts

[ezgranet]

I use Alegreya (such a wonderful typeface!) for my blog, and when I enable discretionary ligatures in CSS after importing the typeface from Google Fonts, I am not seeing the same ligatures I get when enabling dlig on my desktop when downloading the font. I am not sure if this is a server issue or what, but it's a bit annoying as the discretionary ligatures in the typeeface are quite pretty!
