C&W east coast flap this afternoon?

Around 1340 EST today, all four of our C&W connections (1 each of BAR-1
and 2 to both Atlanta/ALD and WashDC/DCK) flapped (physical circuit
down/up) simultaneously, followed by BGP flaps on all four about ten
minutes later.

Anyone else notice C&W getting weird? Or could this be related to the
switchover to New Edge Networks (*grumble*)?


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.
