FYI,

The same problem affects the v6 connectivity of xml.resource.org and 
www3.tools.ietf.org.

Subject: 6bone is still alive (Sprint-SWIP), xml.resource.org down

Hi,

xml.resource.org doesn't work over v6 through Sprintlink (no response to TCP 
SYN), but you can use www2.xml.resource.org (no v6) as a workaround:

$ traceroute6 xml.resource.org traceroute to xml.resource.org

Works fine through C&W:

Hi,

> The same problem affects the v6 connectivity of xml.resource.org and 

Yes.  The IPv6 connectivity to www3.tools.ietf.org a.k.a. www3.xml.resouce.org
was down from ~14:30 CET Monday to 17:30 today.  I haven't found out exactly
what was wrong yet -- called in a trouble report yesterday, though.
