AWS Cooling Failure Outage

The update mainly tightens the framing of the AWS incident: it remains a localized Northern Virginia outage, but the current version more explicitly ties the disruption to cooling-system failure and notes recovery work bringing additional cooling capacity online. The broader interpretation is unchanged, though the operational emphasis on facility-level heat rejection is clearer.

The update sharpens the outage mechanism by adding explicit power loss alongside overheating and identifies the affected zone more precisely. It also reframes the impact as broader service degradation within one availability zone, with downstream customer disruption remaining part of the story.
