Regarding the Anti-DDoS cloud cleaning solution; which of the following statements is wrong?

Ordinary attacks will usually be cleaned locally first.

If there is a large traffic attack on the network, send it to the cloud cleaning center to share the cleaning pressure.

Since the Cloud Cleaning Alliance will direct larger attack flows to the cloud for cleaning, it will cause network congestion.

The closer to the attacked self-labeled cloud cleaning service, the priority will be called.
