I don't know what Google and Moratel's peering agreement, but "leak"? educate me, Google is announcing /24 for all of their 4 NS prefix and 8.8.8.0/24 for their public DNS server, how did Moratel leak those routes to Internet?

Where did you get the idea that a Moratel customer announced a google-owned prefix to Moratel and Moratel did not have the proper filters in place? 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?
Hint: Don't say No-Advertise, unless you want peers to only talk to the adjacent AS, not their customers or their customers' customers, etc.
Looking forward to your answer.

What do you mean hijack? Google is peering with Moratel, if Google does not want Moratel to advertise its routes to Moratel's peers/upstreams, then Google should've set the correct BGP attributes in the first place.
That doesn't make the slightest bit of sense.
If a Moratel customer announced a Google-owned prefix to Moratel, and Moratel did not have the proper filters in place, there is nothing Google could do to stop the hijack from happening.
Exactly what attribute do you think would stop this?

Another case of route hijack -

I am curious if big networks have any pre-defined filters for big
content
providers like Google to avoid these? I am sure internet community would be working in direction to somehow prevent these issues. Curious to know developments so far.
Thanks.
