It looks like facebook is having DNS troubles. The www.facebook.com subdomain is delegated to some servers that are no longer answering. Also apps.facebook.com is a cname to www-college.facebook.com which gets no reply. Maria

Whois query gets us: NS2.FACEBOOK.COM 204.74.67.132 DNS05.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: SERVFAIL This 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. --p Darden, Patrick S. wrote:

a) why are you relying on whois for stuff that's authoritative in DNS? b) isn't this what the outages list is for?

Sorry - my bad - I will post to outages in future. Digs to name servers were showing similar results to Patrick's below. However, it seems to be fixed now. Maria On May 21, 2009, at 12:56 PM, John Payne wrote:

I don't know that it's a DNS issue. I had trouble reaching facebook.com and www.spc.noaa.gov for a while, as well as a couple IPs in Chicago on residential Comcast. Had issues for about the last half hour but seemingly all is well now. I hope. -Andy Ringsmuth

No, when you do a whois for 'fakebook.com' it will pull any registered NS entries containing facebook.com anywhere in the whois db. Digging a.gtld-servers.net is the best way to find authoritative NS for facebook.com, not whois. Clay Haynes wrote:
