Looks like Amazon is experiencing some connectivity issues this morning in their N. VA east 1 data center where LR is hosted.
If you're having problems connecting to LR, please check the amazon dashboard here:
http://status.aws.amazon.com/ to see if their issues has been resolved.
I am able to connect intermittently, but it is hit or miss.
Thanks,
