OpenAI blames a “recent telemetry service” that failed for considered one of the longest outages in its history.
On Wednesday, OpenAI's AI-powered chatbot platform, ChatGPT; his video generator, Sora; and its developer-focused API experienced significant disruption starting at roughly 3:00 p.m. Pacific Time. OpenAI recognized the issue soon after and started working on an answer. However, it might take the corporate about three hours to revive all services.
In an autopsy published Late Thursday, OpenAI wrote that the outage was not attributable to a security incident or a recent product launch, but by a telemetry service the corporate deployed on Wednesday to gather Kubernetes metrics. Kubernetes is an open source program that helps manage containers or packages of apps and associated files used to run software in isolated environments.
“Telemetry services have a really long reach, so configuring this recent service inadvertently caused… resource-intensive Kubernetes API operations,” OpenAI wrote within the postmortem. “(Our) Kubernetes API servers were overwhelmed and brought down the Kubernetes control plane in most of our large (Kubernetes) clusters.”
That's a variety of jargon, but essentially the brand new telemetry service impacts OpenAI's Kubernetes operations, including a resource that most of the company's services depend on for DNS resolution. DNS resolution converts IP addresses into domains. For this reason, you’ll be able to type “Google.com” as a substitute of “142.250.191.78.”
OpenAI's use of DNS caching, which incorporates details about previously searched domains (e.g. website addresses) and their corresponding IP addresses, complicated matters by “delaying visibility,” OpenAI wrote, and “the “The introduction of (the) enabled telemetry service would proceed before the complete extent of the issue was recognized.”
OpenAI says it was in a position to detect the difficulty “a couple of minutes” before customers actually noticed the impact, but that it was unable to quickly implement a fix since it needed to work around overloaded Kubernetes servers.
“This was a coincidence of multiple systems and processes failing concurrently and interacting in unexpected ways,” the corporate wrote. “Our testing didn’t capture the impact of the change on the Kubernetes control plane (and) the remediation was very slow on account of the lockdown effect.”
OpenAI says it can take several measures to stop similar incidents from occurring in the longer term, including improvements to phased rollout with higher monitoring of infrastructure changes and recent mechanisms to make sure OpenAI engineers are attentive to Kubernetes under all circumstances.

“We apologize for the impact this incident has had on all of our customers – from ChatGPT users to developers to corporations that depend on OpenAI products,” OpenAI wrote. “We fell in need of our own expectations.”
