My EC2 instance is blocking all outbound connections.

wget http://www.google.com  ==> Hangs
ping google.com ==>hangs
ssh user@anyserver ==>hangs

I ran : sudo iptables -F to eliminate all rules to no avail

AWS Management console shows Security Group for that instance has Inbound rule allowing ssh and port 80. Can't find anything about Outbound rules there.

Rebooted instance, no change.

If anyone knows how to diagnose or fix, please help.

Adding info:
