ipv6.level3.com has been responding with a "500 Internal Server Error" since Saturday morning. I reached out twice to the NOC email address I have on file, but no response.
Perhaps someone can reach out to the right person. Frank P.S.: ipv6.cnn.com has not been responding properly for about two-thirds of this month, starting December 7, early a.m. I've reached out to my Turner contact at least twice, but not luck there, either.
