The signing service is not here yet.

This address is reserved for the IDDⁿ signing service. It will let a person ratify an item with a key their own device holds, so that the ratification can be checked by anyone, later, without asking this service. It has been specified and is not yet built.

Nothing else will ever be served from this address.
