AWS timestream documentation change

Service: timestream · 2026-03-13 · Documentation medium

File: timestream/latest/developerguide/s3-vpc-endpoint-private-clusters.md

Summary

Added notes recommending that the S3 VPC endpoint for Timestream for InfluxDB private clusters be associated with a VPC hosting only those databases and stating that shared VPCs are not currently supported for Timestream for InfluxDB 3.

Security assessment

These notes provide security guidance for network isolation (preferring dedicated VPCs) and clarify a current limitation (no shared VPC support). This promotes security best practices like network segmentation to reduce attack surface and potential lateral movement, but there is no mention of a specific vulnerability being patched.
