Option B uses the available historical evidence at the same scope as the capacity decision. ZIA dashboards can track anomalous usage trends, and the Executive Insights report reports bandwidth consumption by location. Zscaler’s widget guidance recommends line charts for bandwidth-usage trends, while Bandwidth Control documentation provides location-level sizing and allocation practices. Repeated saturation at the same sites and periods indicates that capacity or circuit design requires targeted remediation rather than an arbitrary global policy change. Waiting for complaints is reactive and loses the advantage of months of telemetry. Reclassifying critical business applications can reduce their priority and violate performance objectives. Relaxing controls without confirming the bottleneck may allow recreational traffic to compete more aggressively. Trend-based capacity planning addresses persistent constraints while preserving intentional application prioritization.
