Introduction

The sudden 30% increase in support tickets related to DigitalOcean Spaces in the last 24 hours is a critical issue that demands immediate attention. This analysis will systematically identify, validate, and address the root cause while considering both short-term fixes and long-term implications for our cloud storage service.

I'll approach this problem by first clarifying the context, then ruling out external factors before diving deep into our product ecosystem, user journey, and potential internal causes. We'll generate data-driven hypotheses, conduct root cause analysis, and develop a comprehensive plan to resolve the issue and prevent future occurrences.

Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to a recent deployment. Have there been any updates or changes to the Spaces service in the past 48 hours?

Why it matters: Recent changes often correlate with sudden spikes in support tickets. Expected answer: Yes, there was a minor update to the API. Impact on approach: If confirmed, we'd prioritize investigating the update's impact.

• Considering the scale of the increase, I'm wondering about the nature of these tickets. Can you provide a breakdown of the most common issues reported in these support tickets?

Why it matters: Understanding the types of issues helps narrow down potential causes. Expected answer: A mix of upload failures, slow performance, and access issues. Impact on approach: This would guide our focus on specific components of the service.

• Given that Spaces is a storage service, I'm curious about usage patterns. Has there been any unusual spike in usage or data transfer in the last 24-48 hours?

Why it matters: Abnormal usage could indicate a potential cause or exacerbating factor. Expected answer: Usage has been within normal ranges. Impact on approach: If usage is normal, we'd focus more on internal systems rather than capacity issues.

• Considering potential external factors, I'm wondering about our infrastructure. Have there been any reported issues with our underlying cloud infrastructure or CDN providers?

Why it matters: External dependencies can sometimes cause cascading issues. Expected answer: No major outages reported from our providers. Impact on approach: This would help rule out external factors and focus on our systems.
