Applicable services: Anti-DDoS Premium
Time: (UTC+8) 10:00:00 to 12:00:00 on December 19, 2019
Description: The software of data centers in Singapore where Anti-DDoS Premium deployed is upgraded.
Impact: During the upgrade, connections to some IP addresses need to be reestablished. This breaks the TCP-based connections one 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 submit a ticket.
