Why has Sportradar's live odds feed experienced a 15% increase in latency over the past week?

Introduction

Sportradar's live odds feed latency increase of 15% over the past week is a critical issue that demands immediate attention. This performance degradation directly impacts the core value proposition of real-time sports betting data, potentially affecting customer satisfaction and revenue. I'll approach this problem systematically, focusing on identifying the root cause, validating hypotheses, and developing both short-term fixes and long-term solutions.

Clarifying Questions (3 minutes)

• Given the sudden increase, I'm wondering about recent system changes. Have there been any significant updates or deployments to the odds feed infrastructure in the past two weeks?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, a new caching layer was implemented. Impact on approach: If confirmed, I'd focus on the new component's integration and performance.

• Considering the specificity of the 15% figure, I'm curious about our measurement precision. Has there been any change in how we measure or calculate latency recently?

Why it matters: Ensures we're addressing a real issue, not a measurement artifact. Expected answer: No changes in measurement methodology. Impact on approach: If changed, we'd need to reassess the actual performance impact.

• The timing makes me think about potential external factors. Have we seen any unusual spikes in traffic or changes in usage patterns coinciding with the latency increase?

Why it matters: External factors could be straining our systems. Expected answer: Traffic has been within normal ranges. Impact on approach: If traffic spikes are detected, we'd need to investigate capacity and scaling issues.

• Thinking about the broader ecosystem, I'm wondering if this is isolated to the live odds feed. Are other Sportradar products or services experiencing similar latency issues?

Why it matters: Helps determine if this is a localized or systemic problem. Expected answer: The issue appears to be specific to the live odds feed. Impact on approach: If widespread, we'd need to consider broader infrastructure or network issues.
