# AgentCore Web Search adds Ohio, Oregon, Sydney and GovCloud (US-West) > AWS expands Amazon Bedrock AgentCore Web Search to four more Regions, including GovCloud (US-West), widening placement options for web-grounded agents. Canonical URL: https://www.devobs.io/news/news-event-09e76ad01bfc0792ed8484b4/ By: Jonah Reed Published: 2026-10-16T12:42:58.040Z Updated: 2026-10-16T12:42:58.040Z Event date: 2026-10-15 Section: AI AWS [announced on October 15, 2026](https://aws.amazon.com/about-aws/whats-new/2026/10/amazon-bedrock-agentcore/) that Web Search on Amazon Bedrock AgentCore is now available in four additional AWS Regions, including AWS GovCloud (US-West). ## Newly supported Regions The announcement names: - US East (Ohio) - US West (Oregon) - Asia Pacific (Sydney) - AWS GovCloud (US-West) AWS describes Web Search as a fully managed tool that provides AI agents with current information from the web for research, summarization and question answering. This is a regional availability update to that tool. ## Evaluate latency across the whole workflow For engineers, the practical change is a wider choice of Regions for the web-retrieval step in an agent workflow. [AWS says](https://aws.amazon.com/about-aws/whats-new/2026/10/amazon-bedrock-agentcore/) retrieving information closer to applications and end users can lower latency, but the announcement provides no measurements. Treat that claim as a reason to evaluate placement, not as a quantified performance guarantee. Before moving a workload, compare end-to-end response times, including model inference and other tool calls. Measure the retrieval step separately to determine whether any improvement there meaningfully changes the total response time. ## Review GovCloud suitability for each workload [AWS positions the GovCloud (US-West) addition](https://aws.amazon.com/about-aws/whats-new/2026/10/amazon-bedrock-agentcore/) as an option for government workloads with compliance and data-residency requirements. Treat regional availability as a starting point for review, not as a workload-specific compliance determination. Before adopting the tool, validate the proposed data handling against your workload’s compliance and residency obligations. The GovCloud expansion named in this announcement is specifically US-West. ## Source references -
