Typekit.net (presumably) provides the fonts used, which is useful for caching although LW could also do it locally.
Small comment on this: We have a Typekit subscription, which sadly does not actually allow us to download the fonts and serve them locally. We have to serve them directly from Adobe’s servers. It’s slightly annoying, but I don’t think it’s bad enough that I would want to stop using Typekit (which has overall been pretty decent and gives us access to a really wide range of fonts).
