Global Retailer Rescued from Critical Black Friday Outage
Client Overview: A multi-national fashion retailer with $500M+ in annual revenue faced a catastrophic database failure just 12 hours before their biggest sales event of the year.
The Problem
The client's legacy Magento installation could not handle concurrent user spikes, leading to a complete checkout freeze and data synchronization errors between the site and their ERP.
Critical Challenges
- Imminent high-traffic sales window
- Complex legacy code with no documentation
- Synchronization lag with global warehouses
- High risk of lost customer credit card data
The Solution
We deployed a dedicated POD of 5 senior Magento architects and 2 DevOps engineers. Using AI-enabled log analysis, we identified a deadlocking SQL query and implemented a caching layer within 4 hours. We then established a temporary load balancer to distribute traffic across redundant server nodes.
Measurable Outcomes
- Zero downtime during the 48-hour sales event
- Page load speed improved by 45% post-fix
- Highest revenue Black Friday in company history
