Google took one of its servers out of service.  The ip addr seemed to be cached
and foxfire didn't perform a fresh lookup before giving up on connecting saying
" could not be found, please check the name and try again"

nslookup found an ip for, ping proved it alive.

Reproducible: Always
Steps to Reproduce:
1.find a server that will be taken out of service
2.dns resolve that server
3.try to connect to the server once its been taken out

Actual Results:  
" could not be found, please check the name and try again"

Expected Results:  
Perhaps if one can't find a route to a host one might try re-resolving.  Perhaps
it is that is taking their servers out of service prior to the
expiration of their TTL.  Perhaps a good failsafe would be to try to initiate a
fresh dns lookup after connection failure with the dns server responsible for
the domain in question and if the results are different attempt to connect there.
