Many data-driven companies struggle with tracking anomalous behavior in their KPIs, let alone their more granular metrics, because traditional BI tools just can’t keep pace with big data. Manual processes, whether monitoring dashboards or setting static thresholds, often leads to missed incidents or prolongs time to resolution.

Many incidents get resolved before they make headlines. But there are plenty that go on to wreak havoc on users and damage the brand. We track glitches impacting the world’s most prominent companies to underscore the importance of anomaly detection – and as a warning against denial. Because if it can happen to the world’s biggest brands, it can certainly happen to you.

Here are the incidents that took their toll in May:
