FYI - it's also the main IPv4 site, not just IPv6... although I'm unsure if it's the same issue. I was monitoring availability as a point of reference for my network and started receiving 500 errors recently as well that tripped up the monitoring system, even though the page comes up in any browser I try. GET / HTTP/1.1 User-Agent: Mozilla/4.0 (compatible; MSIE 4.01; Windows NT) Accept: */* Host: www.level3.com HTTP/1.1 500 Internal Server Error Connection: Keep-Alive Set-Cookie: ISAWPLB{98EBD5B9-3291-4747-849D-EABBFCE6EAA5}={895C6EC5-4BFE-48F4-A0A2-3393F2E8CF2F}; HttpOnly; Path=/ Content-Length: 3026 Date: Tue, 20 Mar 2012 14:33:53 GMT Content-Type: text/html; charset=utf-8 Server: Microsoft-IIS/7.5 Cache-Control: private X-AspNet-Version: 2.0.50727 X-Powered-By: ASP.NET This is followed by a typical obfuscated ASP.NET application runtime error. I just chose a different reference point to monitor and didn't really dig into it much more than that... -Vinny -----Original Message----- From: Philip Dorr [mailto:tagno25@gmail.com] Sent: Tuesday, March 20, 2012 5:41 AM To: Frank Bulk Cc: nanog@nanog.org Subject: Re: Website for ipv6.level3.com returns "HTTP/1.1 500 Internal Server Error" Chrome, Konqueror, and Firefox load the page fine.

Email to Level3's "DL-IPV6-Support@Level3.com" has gone unanswered, so perhaps someone on this list can prompt the right group at Level3 to look at this:
