YouTube CDN down?

[Blair Trosper <blair.trosper () gmail com>]

Suddenly having an inability to play YouTube videos over IPv4 and IPv6 from
multiple ASNs in multiple locations in the United States.  Tried multiple
operating systems and browsers...all have the same issue.

(The very few that do play stall out, even though they're buffered.)

Is this just me, or is there an issue afoot?
