Dear Alibaba Cloud User,
Alibaba Cloud will upgrade the access log system for Object Storage Service (OSS) in the US (Silicon Valley), US (Virginia), and Singapore regions. The maintenance is scheduled from 00:00:00 on November 10, 2025 to 23:59:59 on November 30, 2025 (UTC+8). During the upgrade, a small number of access logs may be lost for a period of one to three minutes. This may affect monitoring data for CloudLens for OSS and log data from real-time LogSearch in these regions. Normal feature operations and the OSS log storage feature are not affected by this upgrade.
We apologize for any inconvenience this may cause. Thank you for your continued support.
