Indeed the backend useable by U1Db was not shut down. Unfortunately 
however all documentation is gone so I sympathize with the fact that 
it's basically impossible to discover that the servers are still 
running.

https://u1db.one.ubuntu.com/~/test.db

That's what the API endpoint looks like. It won't work as-is in a 
browser because it requires OAuth. This was also at the time one of the 
challenges in making it work, since the authentication methods were 
being implemented in online accounts in parallel to U1Db QML bindings 
adding support for synchronization. So the code was mainly implemented 
based on a local server, which was easy to run. But it wasn't 
straightforward how apps would authenticate, including signing the API 
URLs, and ideally, be able to use any server of the user's choosing.

The sync branch didn't make it past proof of concept - see 
https://code.launchpad.net/~uonedb-qt/u1db-qt/syncWithU1 - it basically 
works but the code needed cleaning up when my time then was 
increasingly going into UI Toolkit work, and the aforementioned design 
problems are still unsolved.

I'd be very happy to see this work being picked up if there's enough 
interest, especially with concrete use cases to solve, as looking back 
the original API was not written in the best possible way, especially 
the Synchronizer.

ciao,
