Today between 1:35 PM and 1:45 PM MST, the core routers which handle all XMission and Stackable traffic to and from the Internet experienced an overload which caused sporadic traffic outages during this time period.
 
XMission has redundant routers with connectivity to several Internet backbone providers. Currently only one of these is IPv6 capable. During an attempt to bring the second router online with IPv6, it caused high CPU use and overload which caused processing all traffic to slow. As soon as the overload was noticed, the changes were undone.

This was a minor network change that was not expected to cause any problems. XMission will hold off conversion of this second router until they find a resolution as to why the routers overloaded. This change will be executed during off hours just to be certain. Both XMission and Stackable apologize for any inconvenience caused due to this outage.
