Amazon AWS has reported that this issue has now been resolved. The reason for the outage was because one of their datacenters had been impacted by a malfunction in the air cooling handlers. This caused the majority of devices to overheat, and thus shutdown. In addition to this, an automatic fire suppression system triggered within the facility, which prohibited the on-site operators to access the devices directly.
