How Do I Unblock an EIP?

If the bandwidth of an EIP exceeds a certain threshold or an attack (usually a DDoS attack) occurs, the EIP will be blocked.

Generally, as long as there are no attacks, blocked EIPs will be automatically unblocked 24 hours later. To unblock the EIPs in advance and prevent attacks, you need to configure Advanced Anti-DDoS.

If the blocked EIP is continuously attacked, assign a new EIP and release the blocked one. For details, see How Can I Unbind an Existing EIP from an Instance and Bind Another EIP to the Instance?
