Again none of these following links will work unless you are setup to use the alternate DNS.
grep.geek - Currently the only search engine I could find. openniclist.ing - A website listing, similar to dmoz.org monitor.ing - A website that monitors the openNic servers across the world and allows you to see any problems.
This last one you can actually visit - it explains how to setup and use the alternate DNS on your hardware. www.opennicproject.org
