On May 7 and 8, 2026, a thermal event in a single AWS data center hall knocked out power to EC2 instances and EBS volumes in a single Availability Zone in us-east-1. Within hours, more than 150 cloud services went down, including Coinbase, Reddit, HubSpot, and Atlassian's suite of tools, Jira, Confluence, and Trello among them. For teams without a structured cloud outage response workflow, the next several hours looked familiar: Slack DMs asking "is it down for you too?", tab-switching between status pages, and incident commanders repeating the same update in three different channels.
