In our setup we have 2 hidden masters and all Anycast-slaves have 
configured both masters.

If one hidden master is down, I see that some slaves "fall behind" as if 
they were still checking the currently not availble master. That's why I 
asked. Do you know if this is a new feature? Maybe I have to update the 
slaves.
