Yep, sure was.

Supposedly it has to do with wedging the input buffer. 75 malformed
packets lock it up. It may not in itself cause a reload but one may
be needed to recover.
It's all over IRC, not a peep yet from Cisco. Rumor is that they've
given advance notice to the major backbones and the rest of the world
won't become enclued until late tomorrow afternoon.
In other news, AT&T experienced some major flakiness a couple of hours
ago, and released a very vague statement about "some customers may have
experienced an impairment..." Their woes were rumored to be a fiber cut
but I haven't heard of any voice or non-IP AT&T problems.
