Upgrade time: Beijing Time 10:00 on Feb 14, 2022 - Beijing Time 18:00 on Mar 11, 2022

Upgrade content: Alibaba Cloud PrivateZone System Upgrade in India Region.

Upgrade impact: If you added a private zone which switched on 'Subdomain recursive resolution proxy' and added a wildcard hostname, it will change the resolution behavior and give the different results after this upgrade. Before this upgrade, if the DNS request domain name hit the rule of this wildcard hostname, PrivateZone system would ignore this configuration and process recursive dns query routine, then give the response. After this upgrade, if the DNS request domain name hit the rule of this wildcard hostname, PrivateZone system would give the response according this wildcard hostname‘s dns configuration. If you don't want this wildcard hostname to take effect, please delete it before this upgrade time.
