We're seeing some strange issues with our fiber connection to TWC in Ohio. Intermittent packet loss to/from some IPs.

It gets as specific as from a certain IP outside our network, packets to a.b.c.10 are fine, but pings to a.b.c.50 
(same subnet of same netblock) lose ~75% of the packets.

Likewise, from one of our IPs, connections are fine to a particular remote host, but not to another host on the same 
network.

Connections to/from some other IPs (and some whole networks) are totally fine.

It almost seems that some piece of gear somewhere is barfing on packets that have a particular set of bits in the 
source and/or destination address.

LACP somewhere with a partial link failure?
