Since this is January 26, 2012 it's been gone for almost a month. I have a Garmin Nuvi 1490LMT, but it uses Navteq and the Traffic alerts still work.
On a side note, however, the service seems to me to not yet be ready for prime time. It's often late in reporting slowdowns and late in updating statuses.
