August 2026 Summaries

On August 13, 2026, utility fluctuations and city grid outages caused a Phoenix data center to lose cooling, leading temperatures to rise and much of the region’s compute, storage, caching, sticky disk, and static IP infrastructure to fail. Storage clusters lost quorum first, causing cache-dependent jobs to hang until caching was manually disabled, while approximately 2,400 compute hosts became unavailable and remote management systems prevented direct recovery until early August 14. Workloads were shifted to other regions, preserving service availability but increasing queue times across the network, with tens of thousands of jobs waiting in Phoenix and Ashburn and some larger runners remaining unscheduled for hours. GitHub Actions job adoption in Phoenix returned near normal by 21:45 UTC on August 13, while storage-related services were restored by 18:09 UTC on August 14 after remote access enabled power cycling and recovery work. Planned improvements include distributing capacity across more facilities, automatically bypassing unavailable storage rather than allowing jobs to hang, and making incident-response configuration changes possible without service redeployments.

Blacksmith announced a $45 million Series B financing led by Peak XV, with existing investors Y Combinator and GV increasing their support, valuing the company at $550 million in a round completed in March 2026. The company says adoption of AI coding tools, particularly following the release of Claude Opus 4.5, has sharply increased software output and CI demand, with jobs on its platform growing 5–10% weekly and customers reporting major increases in pull-request volume and infrastructure strain. More than 6,000 companies, including Supabase, Clerk, Ashby, and Mercury, now use Blacksmith’s CI platform. Building on its original focus on high-performance CI infrastructure, Blacksmith is expanding into tools designed to validate and merge code faster, including its code[smith] cloud coding agent, which can build features, fix bugs, diagnose CI failures, and help maintain pull-request health, as well as a planned autonomous QA product. The new funding will primarily support a substantial expansion of its compute capacity, currently measured in hundreds of thousands of cores, and the company is hiring in New York City and San Francisco.
