We see instability from certain prefixes originated by C&W around this
time (indeed, they seem to be showing up across many of our views).  See


for example.  Other views at AS 3130, 11085, etc. show similar flapping
around that time for the same prefixes.  However, we don't see
widespread C&W flapping at that time.
