Lessons from Recent Outages: How Smart Enterprises Stay Ready
Zscaler, Monday, September 21st, 2026
Zscaler describes how its ZDX tool pinpointed a Salesforce application issue within minutes during a September outage.
Zscaler notes that Microsoft, Google Cloud and Salesforce all suffered significant outages in recent weeks, including a September 16 Salesforce authentication failure that took down its CRM, APIs and support portal for nearly three hours across six countries.
During that incident, Zscaler Digital Experience (ZDX) detected a sharp drop in Salesforce Lightning experience scores while network latency stayed steady, immediately showing IT teams the problem was the application, not the network.
Using the ZDX Agent, teams identified the root cause within minutes instead of the hours manual investigation would typically take. Zscaler frames end-to-end visibility as the difference between resilient enterprises and reactive ones during unavoidable outages.
