Private workloads reach nothing they depend on
Everything running in the private tier has gone quiet: it cannot reach the open network, shared storage, or the database behind it, while the public tier keeps answering normally. Connections simply never complete. Recent changes touched routing and traffic rules across several layers at once. Restore outbound reach for private workloads across every dependency they need.
Where the symptom shows: EC2
Take this challenge on a live account
A live AWS account, already broken, and a clock. You fix it with the provider's own console and command line, then read a report of how you worked. We host the cloud account. Nothing lands on your bill.
