Grant, We have been having issues for a few weeks now with instances that randomly stop getting their IP from DHCP. Did you see any dhcp errors?

Hi, Over the last 6 hrs i have had over 100 instances in us-east-1 in EC2 Classic fail their instance health checks and a reboot via the console solves them. Logs on the host point to a loss of all network connectivity. Anyone else experiencing something like this? Reached out to AWS support and haven't gotten anywhere with that yet. -Grant
