MICE Google Global cache issues?

Hi, Since Monday we've been having issues with mobile devices accessing YouTube and Google Play store via IPv6. Our symptoms with YouTube app is mostly with Apple IOS devices. When a user loads a video, the ads will play fine and then the video will start and play for 5 seconds and stop. Browsing youtube via a web browser on the IOS devices seems fine. With Android devices, users can't download apps from the play store. Is anyone else experiencing these issues with their peering with the Google Global Cache at MICE?
