Applicable services: Anti-DDoS Premium

Time: (UTC+8) 17:00:00 to 21:30:00 on December 5 and 6, 2019

Description: The network of data centers in the eastern United States where Anti-DDoS Premium is deployed is upgraded.

Impact: During the upgrade, connections to some IP addresses need to be reestablished. This breaks the TCP-based connections two to four times. Transient disconnection errors have little impact on services that use short-lived connections and persistent connections that can be automatically reestablished. Make sure that your services support automatic reconnection to ensure fault tolerance.

Customer service: We apologize for any inconvenience caused. If you require any further assistance, we recommend that you contact customer service.
