The download link for the map that was released last year as part of the 10 year celebration for the Java Edition no longer works, it shows a "404 Not Found" error when trying to download.

The map can still be downloaded from the Marketplace for the Bedrock Edition, I am unable to check if it can still be found on Java Realms.
You can still get the map on the Blockworks page.
