For some reason one my instances has become problematic. The error is:
Instance reachability check failed
I've tried rebooting and stopping and starting. Neither of these operations worked. I figured it might be some sort of network issue and decided to create a new AMI from the faulty instance. I then launched the instance but it appears to have exactly the same problem as the original instance (I guess I cloned the problem too?).
Anyhow.... now I'm basically stumped. I'm guessing my only option is to create a brand new instance from a fresh image, mount the old hard-drive and copy things across. The amount of sysadmin I'd have to re-do though scares the crap out of me.
Do I have any other options available to me?
