Could someone from Amazon Web Services contact me off list? You appear to be having connectivity problems on the private network (10.0.0.0/8) at US-EAST-1 between two or more zones, causing dozens of alarms and failures over the last 2-3 hours...however, there is no notation on the status page or any hint whatsoever of the problem.
(The alarms are coming from the instance checks on the instances...which is the network...not the status checks...which would be the instance's health inside the PVM virtualization.)
