Youtube streaming issues lately

Lately, Youtube has been having streaming issues.  I have noticed it on both my MK802 IIIs as well as on my laptop.  I didn't know if it was my network or if it was Youtube itself.  I was travelling recently and I brought my old MK802 II with me.  I was in a different state, and Youtube was still having issues.  HD almost never plays.  I end up switching to SD at the start of every video.  Even in SD mode, many videos were buffering.  The commercials tends to have a worse time with buffering.  This annoyed me greatly since Sony is running an ad campaign to launch the PS4.  This campaign seemed to play a commercial for every video I tried to watch.  If Youtube wants to launch Premium Channels, then they will need to step up their game.  End users will not pay for channels if they buffer.
