Seen it happen before, and it was on Ormuco's hardware...Time Warner contacted them for me and it got resolved a few days later.
The trick was I was working with TWC's Tier3 techs to track it down though...was nothing to do with SE, but a problem amongst the involved ISP's and their routing policies.
