In May 2025, thousands of Tesco customers were left frustrated as the retailer's app and website went offline without warning. The outage disrupted account logins, checkout processes, and access to loyalty programs like Clubcard. Reports surged on platforms like DownDetector, with users receiving repeated “something went wrong” errors and being unable to manage their online orders.
While Tesco acknowledged the issue and worked on a fix, this incident highlights a critical truth for today’s digital economy, even the largest brands are vulnerable to technical breakdowns.
For businesses relying on apps or online portals to engage customers, an outage can mean more than lost sales, it can damage trust, reduce user retention, and expose gaps in infrastructure.
At Don Clem Technology Ltd, we believe digital resilience is no longer optional. From scalable cloud architecture and failover systems to performance monitoring and real-time alerts, our software development and DevOps services are built to prevent outages before they happen.
