Summary: RingCentral homepage replaced by 404 error page

Why It Matters: The main landing page for the product is currently broken. This means new customers cannot see product features, case studies, or the 2025 Gartner report.

What Changed:

• The entire homepage content was replaced with a "404 Error - Page not found" message.
• Detailed sections for RingEX, RingCX, and RingVideo are no longer visible.
• The 2025 Gartner Magic Quadrant announcement and AI trends report were removed.
• Customer success stories from the Golden State Warriors and Carbon Health are gone.
• The page now only shows a standard error message with navigation links to other parts of the site.
