Can you provide a source confirming that's the cause of the outage? The timing is suspicious and I suspected it's related, but I wouldn't claim it's the sole cause without confirmation.
If this was related to the outage, it would specifically be evidence that it’s not an “attack”. Government hackers wouldn’t DoS a website by “googling it to death”. That would be nonsensical.
So, this points to potentially just a quick doubling of traffic from some fraction of half a billion people in China.
