Take a bit of advice -- wildly CCing dozens of people is just going to piss
people off and cause them to start ignoring you. You'll get much more
helpful results if you take the time to understand who you need to be
contacting, and contact only that person.
I understand that in the business world it's normal to CC everyone and all
of their managers as well, but that's because in the business world,
politics is more important than getting things done.

I've no idea how that symptom would lead to that conclusion.

I assumed you checked that first.

It certainly does look like Yahoo is blocking you for some reason.
This lends credence to my earlier statement about contacting the correct
person: there's little the FreeBSD team can do about this, you'll have to
contact Yahoo directly.

Unfortunately, ping results are nearly useless in this day and age, because
so many people block ICMP at firewalls as if it's the plague.

Are you unable to reach the mirror sites in Brazil?:
This could be a workaround while you sort out the issue with Yahoo.
Actually, it may be preferable on an ongoing basis.
