It's great to hear that you've experienced an improvement in dataset refresh speed since March 2024. However, the increase in dataset refresh timeout failures is concerning and could potentially be related to the increase in IP ranges used by the West Europe region.
Here are a few points to consider and steps you can take to address the timeout failures:
1. **Impact of Increased IP Ranges:** The increase in IP ranges used by the West Europe region could indeed have an impact on the dataset refresh process. If there are network-related issues, such as increased latency or packet loss, it could affect the performance of data transfer between Amazon Redshift and Power BI Service. You may want to investigate further to see if there are any network bottlenecks or issues that need to be addressed.
2. **Review Power BI Premium Capacity:** While you mentioned that the capacity on Power BI Premium (P2) is below 50%, it's still worth reviewing the resource utilization and performance metrics for your Premium capacity. Ensure that there are no resource contention issues or performance bottlenecks within your Premium capacity that could be contributing to the dataset refresh timeouts.
3. **Optimize Dataset Refresh:** Review the dataset refresh process and look for opportunities to optimize it. This could include optimizing queries, data loading strategies, or data transformation steps to reduce the overall refresh time and mitigate the risk of timeouts.
4. **Engage with Microsoft Support:** Continue working with Microsoft Support to address the dataset refresh timeout failures. Provide them with as much information as possible, including details about the increase in IP ranges, any changes made to the dataset or data source configuration, and any specific error messages or logs related to the timeout failures. While it's frustrating that they haven't been able to provide a definitive solution so far, persistence and thorough investigation may lead to a resolution.
5. **Community Engagement:** Reach out to the Power BI community forums or user groups to see if other users have experienced similar issues since March 2024. Sharing experiences and insights with other users may help identify common patterns or potential solutions.
By thoroughly investigating the potential causes of the dataset refresh timeout failures and engaging with Microsoft Support and the Power BI community, you can work towards resolving the issue and ensuring smooth and reliable dataset refreshes moving forward.
