CPU's were pegged for a customer of mine in California. tracked it
down to 2 events that went down at that time with a large message
volume.
1) Peering between GLBX and Level3 dopped somewhere, causing many
prefixes to shift away from L3 paths.
2) Some IPv6 prefixes were aggressively bouncing from HE starting at
11:25. Can't trace it any further upstream for HE unfortunately.
This cause lots of CPU churn on one of my customers networks
May or may not be related.
