• Looking at the timing, I'm thinking this could be related to a specific event or content. Was there any major live event or popular show premiere during the affected primetime hours?

Why it matters: High-demand content could strain the system. Expected answer: Yes, a popular series finale aired. Impact on approach: Would focus on content-specific scaling issues.

• Considering the scale of the issue, I'm wondering about recent infrastructure changes. Have there been any significant updates to the streaming infrastructure in the past week?

Why it matters: Recent changes often correlate with performance issues. Expected answer: A new CDN was partially implemented. Impact on approach: Would investigate CDN integration and rollout strategy.

• Given the specificity of primetime hours, I'm curious about user behavior patterns. Has there been any notable shift in viewing habits or subscriber numbers recently?

Why it matters: Unexpected user behavior can overwhelm systems. Expected answer: Subscriber growth has been steady, no major changes. Impact on approach: Would look more closely at technical rather than user-driven causes.

• Thinking about the broader ecosystem, I'm wondering if this is isolated to Hulu or if other streaming services experienced similar issues?
