Summary: RingCentral replaces homepage with 404 error page

Why It Matters: The main landing page for the product is currently broken or has been moved without a proper redirect. This prevents potential customers from seeing the primary marketing message and social proof.

What Changed:

• The main headline "The all-in-one AI communications platform" was removed.
• All customer success stories, including the Golden State Warriors and Carbon Health, are gone.
• The 99.999% reliability statistics and Gartner Magic Quadrant leader badges were removed.
• The page now displays a "404 Error - Page not found" message.
• A navigation menu and links to specific products like RingEX and RingCX were added to the error page.
