It has been reported on the Czech Wikipedia ([[cs:Image:Vadné interwiki v rc.JPG]]) that the dsb: interwiki prefix is _sometimes_ not recognized as an interlanguage link, and is displayed as an internal redlink instead.
I have been able to reproduce the problem, and the faulty response has been served from srv60 both times.
So I guess there might be some unsynced interwiki table there, or something.
