This happens occasionally on 8.8.8.8 and 8.8.4.4. We used to use these IPs as Internet reachability tests for determining failover to backup circuits and moved away from it after the first occurrence of this happening.

Glebe Rd, Suite 510 Arlington, VA 22201 From: Outages <outages-boun...@outages.org> On Behalf Of Justin Krejci via Outages Sent: Tuesday, February 8, 2022 2:34 PM To: outages@outages.org Subject: [EXTERNAL] [outages] Ping to Google 8.8.8.8 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.
