No, it's a subdomain with its A records in another server. $ host -t A www.facebook.com glb1.facebook.com. Using domain server: Name: glb1.facebook.com.

Good point Octavio . +trace with dig is always useful when getting weird results. (Sent from my mobile device) Anurag Bhatia http://anuragbhatia.com On Mar 7, 2012 1:19 PM, "Octavio Alvarez" <alvarezp@alvarezp.ods.org> wrote:

We also picked up problems with www.facebook.com from our monitoring systems. Starting from 04:00 UTC there were some latency spikes and then from 06:15 UTC thru 07:55 UTC the site was unreachable. www.v6.facebook.com had no issues though ;) -- Graham Beneke
