Till now when a server was in the "blocking regime" there was one probe made every 15 min, to see if this server is up again. In situations where all servers where down (e.g. because of a massive package loss) it could take up to 15 min to have a working dns again.

This patch changes this behaviour in a way that a server marked down is probed every 2 min.

Fixes: #12557
