Satar,
Yes, things have changed. The fiber enablement is 100% now, it
was not fully fiber before. Believe it or not the information
that I posted is also from the horse's mouth. This individual is
a very senior person in their database management space. I am
sorry, but I cannot provide confidential configuration
information of Yahoo or any other customer on a public list like
this.
Thanks for your understanding,
Gaja
