It wasn't.  The router feeding us has a built-in throttle to stop multicast
routing if the number of DVMRP routes gets too large.  The threshold was set
at 3500 and was crossed, subsequently all our routes disappeared.  The
threshold's been pushed up a bit.

nosey is running 11.0.5 and comm-g is running 11.0.7.  I'll drop a line
to cisco.  Thanks for the response.

Sean wasn't wearing the baseball cap backwards last time I saw him at NANOG,
but otherwise, you just described his attire.
