Neil / Dovid,
How long ago did your issues start? Symptoms are the same, but the issue
for me started early this morning at an alarming rate.

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
