Could be residual from this incident yesterday? AWS claims it's been resolved, though.
[RESOLVED] Instance Connectivity 3:13 PM PST We are investigating connectivity issues for some instances in the US-EAST-1 Region. 3:33 PM PST We can confirm connectivity issues when using public IP addresses for some instances within the EC2-Classic network in the US-EAST-1 Region. Connectivity between instances when using private IP addresses is not affected. We continue to work on resolution. 4:00 PM PST We continue to work on resolving the connectivity issues when using public IP addresses for some instances within the EC2-Classic network in the US-EAST-1 Region. For instances with an associated Elastic IP address (EIP), we have confirmed that re-associating the EIP address will restore connectivity. For instances using EC2 provided public IP addresses, associating a new EIP address will restore connectivity. 6:19 PM PST We continue to work on resolving public IP address connectivity for some EC2-Classic instances in the US-EAST-1 Region. We have started to see recovery for some of the affected instances and continue to work towards full recovery. 7:11 PM PST Between 2:26 PM and 7:10 PM PST we experienced connectivity issues when using public IP addresses for some instances within the EC2 Classic network in the US-EAST-1 Region. Connectivity between instances using the private IP address was not affected. The issue has been resolved and the service is operating normally.
