How DevOps Failed 60K Users

The SlideShare Story

In 2012, I was an operations engineer at SlideShare, part of a team that implemented DevOps practices to accelerate processes and maintain competitive advantage. The company was small — fewer than 20 employees — yet reached 29 million monthly unique visitors, ultimately leading to LinkedIn's $119 million acquisition.

Why DevOps Mattered

Our distributed team spanned San Francisco and New Delhi, with complex infrastructure. DevOps practices created cohesion by requiring contributors to work across different product areas. This approach:

• Broke down geographic barriers through increased collaboration
• Distributed technical knowledge widely, reducing dependency on individual team members
• Minimized disruption when employees took time off or departed

The Critical Failure

A developer was experimenting with a MySQL visualization tool to reorganize database columns for better clarity. Unknown to him, the tool was simultaneously modifying the production database structure and locking it entirely. This brought down SlideShare and prevented over 60,000 users from accessing the service. The team needed 15 minutes to identify the problem's source.

Key Lessons

First, while DevOps emphasizes broad access to infrastructure, organizations must carefully evaluate whether that access genuinely adds value. The developer could have achieved identical results using a staging database with minimal company impact.

Second, comprehensive infrastructure education is essential. Most developers lack exposure to production systems. DevOps success depends on human interaction and shared understanding, making mandatory, thorough onboarding critical.
