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.
We have manually failed over to a backup connection, and are 100% fine now.
I just want to see if anyone has seen anything similar, or has any info. I am on hold now waiting for someone at TWC.
thanks,
-Randy
