Issue
The business suffered high-traffic attacks, causing the IP to be blocked and the business to be inaccessible.
Possible causes
The protection traffic threshold is exceeded, leading to blocking.
The attack is still ongoing, so the IP cannot be automatically unblocked.
Solutions
By default, the IP blocking duration lasts for 2-24 hours (subject to the actual situation). In case of a security emergency, you can apply for Anti-DDoS emergency protection.
