Don't Panic !
If your database was/is on the Australian Heurist server (HeuristRef.net) up to mid Nov 2025,
you will now find it at HeuristAU.net
(this simply points to the same server, nothing else has changed).
If you do not find it there, please try Heurist.Huma-Num.fr
If you are unable to find it, contact us at support@heuristnetwork.org
(we have multiple backups of all servers and can restore them rapidly to any of these servers).
