Let's for a moment contemplate about the sheer magnitude of their operation. With almost 3 billion users worldwide, can you imagine the amount of DNS queries they have to process? Their scale is unprecedented.
That's what I predicted about 20 years ago, which is why I proposed to have anycast name servers analyzing its implications. As such I'm sure anycast route withdrawal ignoring rfc3258 is poor engineering. Scalable solutions can be constructed only with careful theoretical analysis, against which random hacks, which may work 99% of the time, are just harmful. In facebook case, it was combined with poor understanding on short/long expiration period to cause the disaster. Masataka Ohta
