GitHub, the Microsoft Corp.-owned code hosting platform serving more than 180 million developers, is still reeling from a widespread outage on Monday that severely disrupted software development pipelines globally. The hours-long incident was the latest in a relentless series of reliability failures for a service struggling to keep pace with an unprecedented surge in artificial intelligence (AI)-assisted coding traffic. The disruptions began around 9:40 a.m. EDT, initially manifesting as performance degradation across core services. The issue rapidly escalated, causing error rates to spike near 20% for web interface and API traffic, while archive and raw repository content downloads suffered a staggering 50% failure rate. Key capabilities — including GitHub Actions automated testing, webhooks, GitHub Pages, and the AI pair-programmer Copilot — were heavily compromised. Downdetector logged thousands of user reports at the peak of the disruption, with minor outage spikes simultaneousl...
Security belongs in the software delivery pipeline. The harder question is where, how often and at what cost. Many pipeline teams eventually add security scanning to CI/CD, and relatively few go back afterward to measure what it actually cost the delivery process. Security coverage went up. Something else changed too, and it is rarely measured with the same rigor. “Shift left” gets treated as a free upgrade: catch problems earlier, at lower cost, with no real downside. That is true for the cost of fixing a vulnerability. It is not automatically true for the cost of running your pipeline. A security control can be worth adding and still change your delivery economics in ways worth naming honestly, rather than assuming they net out to zero. What Changes When Security Enters the Pipeline SAST, SCA, container scanning, secret scanning, and dependency analysis all do real work, and none of them are free to run. Each one is a pipeline stage with its own execution time, and many scale wit...
