Our instance was deleted

We are using metabase already and have been using metabase for years. We are now experiencing an issue with instance suddenly missing.
We where only deleting dashboards from the trash can inside of the metabase dashboard - the button name was "delete permanently".

Now it show the whole instance is gone, meaning all our dashboards and metabase in general is no longer accesible!

ISSUE IS RESOLVED!
As it was a self-hosted, the server restart solved the issue.
