Yahoo software is a total crap. They use several
computers for their database to split the load
but they can't manage a real cluster where all
computers are synchronized.

That's why sometime you see that an auction
is still runing while it's already closed. Or
you see the wrong highest bidder...

And sometime, whole bunch of auctions vanish
because they are not in the database of the
server you are accessing while it will be ok
for people who access another server. (and
no, you can't choose which server you access).
