Where did you get the idea that a Moratel customer announced a google-owned

according to the blog, all google's 4 authoritative DNS server networks and
8.8.8.0/24 were wrongly routed to Moratel, what's the possiblity for a
Moratel customers announce all those prefixes?
Ah, right, they just leaked Google's prefix. I thought a customer originated
the prefix.
Original question still stands. Which attribute do you expect Google to set to
stop this?

Looking forward to your answer.
I would expect that moratel should have a route object which their
transit providers can construct a prefix filter for. if moratel
advertised an AS path including themselves and a google orgin pccw
should not have accepted it. if they originated the prefix, pccw should
not have accepted it.
