How to cancel data cleaning for an ECS instance

Last Updated: Dec 24, 2018

What is flow cleaning

The flow cleaning service consists of three units: detecting center, cleaning center, and centralized management center.

The detecting center monitors data traffic flowing into the ECS instance, and identifies abnormal traffic in a timely manner, such as DDoS attack. When an abnormity is detected. The management center guides the cleaning center to clean suspicious traffic based on the traffic diversion policy. Malicious traffic is removed, while legitimate traffic is returned to the original instance.

This guarantees that only legitimate traffic can be forwarded to the target system.

How to cancel flow cleaning

  1. Log on to the Alibaba Cloud security console.

  2. Select Anti-DDoS Service > Anti-DDoS Basic, find your ECS instance that is in the flow cleaning status, and click Cancel cleaning.


You can cancel flow cleaning for three times in one day.
