Subject: Packet loss on XO's network

Since ~11:08 am Central our monitoring system has been reporting
intermittent HTTPv6 timeouts to www.sprint.net, www.qwest.com
<http://www.qwest.com> , enterprise.com, and enterprise.ca.  It goes bad for
a while and then clears.

 

Using mtr, these all have XO's network in common, and the packet loss to the
endpoint sustains over 40%.  Seems to be between 2610:18:18b:c000::11 and
mcr1.minneapolis-mn.us.xo.net [2610:18::30b8]
