RE: Operational Issues with 69.0.0.0/8...

We feel your pain, Scott.  We are just glad that we are able to verify that there are problems with this CIDR other than on our network.

Now to get them resolved.  Hopefully this conversation will end up in the proper inboxes to help clean this up.

Does anyone besides me worry that because of the recent cutbacks in this industry that there are orphaned pieces of equipment out there causing some of these problems?

I'd like to second this.  We have ran in to problems as well.  Usually
this is a great place to get help however we have had very responsive
actions taken by others out there who had filters in place.
