Podcasts slow to download

Does anyone else have problems with The Vergecast and Mobile Show downloading really slowly? I've tried Instacast, Downcast, Pocket Casts and the Apple podcasts app on iOS, as well as Pocket Casts and a few others on Android.

The podcasts download really slow on every app, doesn't matter whether I'm on wifi or LTE. Currently downloading Vergecast at 34kb/sec, everything else downloads at a minimum of 1mb/sec.

Anything I can do about this, or anyone else having the problems?
