ICMPv6 to ipv6.google.com went down for me sometime before 9:44 am. Also likely going through MICE (which is in the Minneapolis area). root@nagios:~/bin# traceroute6 ipv6.google.com traceroute to ipv6.google.com (2607:f8b0:4009:80a::200e), 30 hops max, 80 byte packets 1 router-core.mtcnet.net (2607:fe28:0:1000::1) 0.285 ms 0.328 ms 0.385 ms 2 2001:5f8:7f06:d::1 (2001:5f8:7f06:d::1) 0.200 ms 0.203 ms 0.197 ms 3 2001:5f8:7f06:7::1 (2001:5f8:7f06:7::1) 1.731 ms 1.892 ms 1.888 ms 4 AS15169.micemn.net (2001:504:27::3b41:0:1) 18.262 ms 18.284 ms 18.337 ms 5 2001:4860:0:1010::1 (2001:4860:0:1010::1) 17.176 ms * 17.204 ms 6 * 2001:4860:0:1::572b (2001:4860:0:1::572b) 17.191 ms * 7 ord37s34-in-x0e.1e100.net (2607:f8b0:4009:80a::200e) 17.158 ms 17.194 ms * root@nagios:~/bin# ping6 ipv6.google.com PING ipv6.google.com(ord30s21-in-x0e.1e100.net) 56 data bytes ^C --- ipv6.google.com ping statistics --- 6 packets transmitted, 0 received, 100% packet loss, time 5000ms root@nagios:~/bin# Frank From: Outages <outages-bounces@outages.org> On Behalf Of Justin Krejci via Outages Sent: Tuesday, February 8, 2022 1:34 PM To: outages@outages.org Subject: [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.
