G'day Folks

Been having trouble playing Youtube for the last couple of days both on my iPhone and iMac (iMac accesses the internet via an R212 MiFi on 4G).

Friends on other ISPs seem to having no issues. I particularly want to watch https://www.youtube.com/watch?v=4R4StNMsCyQ but Safari consistently gives me the error message "The network connection was lost". (But I can send emails, iMessages etc at the same time without any probs.)

Any thoughts?

Thanks n cheers, Gobit
