1. Availability

Quarter Breakdown

Quarter	Incidents Resolved	Severity Mix	Key Context
Q2 FY26 (Oct-Dec 2025)	331	19 sev1, 63 sev2	Baseline operations. Top affected: profiles (26), education-web (10+), explore (8), lists (8), star (8)
Q3 FY26 (Jan-Mar 2026)	622 (+88%)	29 sev1, 48 sev2	Azure infrastructure changes (wus3 stamp), Conduit incident cascade, cross-DB transaction splits
Q4 FY26 (Apr-Jun 2026)	384 (-38%)	Normalized	Post-incident repairs paid off. Conduit HPA and graceful shutdown reduced repeat alerts

QoQ Change: Q3 saw a near-doubling of incidents due to Azure region migrations and infrastructure experiments. The team invested in structural repairs (Conduit HPA, cross-cluster transaction elimination, timeout fixes) that drove Q4 back below Q2 baseline per-service.
