A major Google Cloud identity outage has caused significant disruptions for AI developers worldwide, knocking popular tools like Replit and LlamaIndex offline. The incident, reported on June 12, 2025, has left many in the tech community scrambling as critical platforms became inaccessible during peak working hours.
The outage, centered around Google Cloud’s Identity and Access Management (IAM) service, triggered widespread API and authentication errors. This affected not only Google’s own services but also third-party platforms that rely on its infrastructure, exposing the fragility of cloud-dependent ecosystems.
Replit, a widely-used online coding environment, and LlamaIndex, a key tool for building AI applications, were among the hardest hit. Developers reported being unable to access projects or deploy code, stalling productivity and sparking frustration across social media platforms.
The ripple effects extended beyond these tools, with reports of intermittent downtime for services like Cloudflare, which depends on Google Cloud for some internal operations. This incident underscores the interconnected nature of modern internet infrastructure and the risks of over-reliance on a single provider.
While Google has yet to release an official statement on the root cause or expected resolution time, posts on X suggest the issue began around mid-morning Pacific Time on June 12. Developers and companies are urged to monitor Google Cloud’s status page for updates as the situation unfolds.
This outage serves as a stark reminder of the importance of cloud redundancy and diversified infrastructure strategies. As the tech industry continues to grapple with such disruptions, calls for more robust failover systems are likely to grow louder in the coming days.
