Clarification here:1/8 was never on the EDS backbone. Was only used locally in one site, as far as I can determine.
They might have done that for other customers as well. (to avoid 10/8 collisions.) Personally, I'd think if they were going to NAT at the edge, they'd only set it up for the machines we were supposed to use, instead, we could see, well, a lot more than we should have.
