On-Call in 2026: Preparing for Cascading Failures
The biggest outages of 2026 are not being caused by a single server dying or one bad deploy. They are being caused by cascading failures, where healthy systems interact in ways nobody planned for and take each other down. That shift changes what good on-call looks like. If your incident response still assumes that "something broke" and one team owns the fix, you are going to be slow exactly when speed matters most.
