appeared this afternoon (Europe) with an instance I rebooted (and then deleted) and with the fresh instance i-0000034b :
cloud-init running: Wed, 18 Jul 2012 13:47:07 +0000. up 5.13 seconds
waiting for metadata service at http://169.254.169.254/2009-04-04/meta-data/instance-id
13:47:10 [ 1/100]: url error [timed out] 13:47:13 [ 2/100]: url error [timed out] 13:47:16 [ 3/100]: url error [timed out] 13:47:19 [ 4/100]: url error [timed out]
So we can not reboot nor access any new instance.
