Use -d to find out why.

The manualroute router thinks it is a really serious error if it can't
find the IP of a host to which you have explicitly routed a domain. It
freezes the message to make you aware of what appears to be a
critical configuration error.

Domains that "come and go" are often caused by multiple nameservers that
are not in step with each other. Double check your nameservers for
cyrus1.
