If he just updated the vBulletin installation, it was possible for an accidental favicon overwrite.
i am eager to see the favicon...i have never seen NB favicon before...
It should be back live soon.
Some recent upgrade override it.
It should be fixed now -- but you may have to reload your browsers to notice.
As Kovich stated, it was overwritten during the recent vBulletin upgrade.
I haven't closed Firefox, so it never disappeared for me.
