Anyone else see access down to ipv6.cogentco.com and www.cogentco.com down
from 4:28 to 4:38 pm (U.S. Central)?  They resolve to the same AAAA, at
least for us.

We recorded ICMPv6 down to www.cogentco.com and HTTPv6 to ipv6.cogentco.com.


None of the other 70+ sites we monitor came into alarm during that time.
