Applicable services: Anti-DDoS Premium
Time: (UTC+8) 01:00:00 to 05:00:00 on May 15, 2020
Description: The network of data centers 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 three 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.
