Sorry guys, I was away from the project for the last few months (?): We moved home !
I apologize for the two "cuts" with this server (2 x ~12 hours), but we had to move the server to a temporary location (thanks RyLe !) and then back to our new Internet connection, and DNS propagation is quiet slow (FYI, the TTL for our 2 DNS zones is now 6 hours to minimize such side effects).
But hey, I used Raydium a lot during this time ... It was very helpful for interior design !
edit : Oww, and Happy New Year everyone !
