Some(or all) aws.amazon.com/about-aws/whats-new lead to 404

The URLs you're encountering 404 errors with are dated 2025, which is in the future. These appear to be example or placeholder URLs that were created for demonstration purposes.

For instance, the URL about Amazon P6e-GB200 UltraServers is dated July 9, 2025, and describes future GPU technology that isn't yet available. Similarly, other URLs with 2025 dates would naturally return 404 errors since they reference content that hasn't been published yet.

AWS typically uses the "What's New" section to announce actual product launches and updates, but these particular URLs with future dates are not accessible because they represent hypothetical future announcements rather than current AWS offerings.

If you're looking for current AWS announcements and product information, I'd recommend visiting the main AWS What's New page without the future-dated paths, or checking the AWS Blog for the latest actual announcements.
