Whois query gets us: NS2.FACEBOOK.COM 204.74.67.132DNS05.SF2P.TFBNW.NET DNS04.SF2P.TFBNW.NET NS1.FACEBOOK.COM 204.74.66.132
both 204.74.67.132 and 204.74.66.132 are pingable, but DNS queries on them directly get various answers:
nslookup www.facebook.com 204.74.66.132 *** Can't find www.facebook.com: No answer and nslookup www.harvard.edu 204.74.66.132 ** server can't find www.harvard.edu: SERVFAILThis tells me the DNS is set up and semi-working, but incorrectly. It answers correctly for a query for a domain outside its purview, but with a "No answer" for stuff it should know.

The www.facebook.comsubdomain is delegated to some servers that are no longer answering. Also apps.facebook.com is a cname to www-college.facebook.com which getsno reply. Maria
