Seeing some hosts and not others get no reply to ICMP pings from the Minneapolis, MN area. I checked using HE's looking glass, 1 of their 2 Minneapolis routers gets no replies. Since many use and assume 8.8.8.8 is invincible, this has now started setting off monitoring alerts. DNS queries so far seem unaffected.
Replying to ICMP echoes is not part of the service Google Public DNS officially does, so it is possible that they sometimes filter and/or rate-limit ICMP echo. It's not an outage.
