Re: network issue on ec2 classic us-east-1??

Hi David and Grant,

        We have been experiencing exactly the same issue also now whereby our
instances randomly stop getting their DHCP reservation and then drop
offline. A simple reboot in the AWS console usually sorts it but as yet we
do not know the root cause.

Regards,
Neil
