Is it that atypical for these public-facing services to drop ICMP when they get hot? I'd not consider it an indicator of service down unless you're getting SRVFAILs James Host Architect - CDN Platform E: jhost@vultr.com On Tue, Feb 8, 2022 at 12:01 PM Christopher Conley via Outages < outages@outages.org> wrote:
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.

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.
