OpenAI is blaming one of thelongest outages in its historyon a “ new telemetry service of process ” gone awry .
On Wednesday , OpenAI ’s AI - powered chatbot political platform , ChatGPT ; its TV generator , Sora ; and its developer - face API experienced major gap begin at around 3 p.m. Pacific . OpenAI recognize the problem soon after and began working on a kettle of fish . But it ’d take the society rough three hour to fix all services .
In a postmortempublishedlate Thursday , OpenAI wrote that the outage was n’t because of a certificate incident or recent ware launch , but by a telemetry inspection and repair it deployed Wednesday to collect Kubernetes metric . Kubernetes is an open source political program that avail manage container , or packages of apps and related files that are used to endure software in stray environments .
“ Telemetry Robert William Service have a very wide footprint , so this novel service ’s configuration unintentionally caused … resourcefulness - intensive Kubernetes API mathematical process , ” OpenAI pen in the postmortem . “ [ Our ] Kubernetes API servers became overwhelmed , take down the Kubernetes control carpenter’s plane in most of our large [ Kubernetes ] cluster . ”
That ’s a lot of jargon , but basically , the new telemetry service affected OpenAI ’s Kubernetes operations , including a resource that many of the company ’s service rely on for DNS resolution . DNS resolution converts IP addresses to domain names ; it ’s the reason you ’re capable to type “ Google.com ” instead of “ 142.250.191.78 . ”
OpenAI ’s use of DNS caching , which holds information about antecedently looked - up domain names ( like internet site addresses ) and their comparable IP addresses , complicated matters by “ delay[ing ] profile , ” OpenAI write , and “ allowing the rollout [ of the telemetry military service ] to proceed before the full scope of the problem was understood . ”
OpenAI say that it was able-bodied to observe the issue “ a few minute ” before customer ultimately depart seeing an impingement , but that it was n’t able-bodied to speedily enforce a fix because it had to work around the overwhelmed Kubernetes servers .

“ This was a concourse of multiple systems and mental process run out simultaneously and interact in unexpected ways , ” the company write . “ Our tests did n’t catch the wallop the change was have on the Kubernetes control plane [ and ] redress was very tiresome because of the locked - out impression . ”
OpenAI says that it ’ll adopt several metre to preclude similar incident from occurring in the future , include improvements to phased rollouts with good monitoring for base changes and raw mechanisms to ensure OpenAI engineers can reach the ship’s company ’s Kubernetes API servers in any circumstances .
“ We apologize for the impact that this incident caused to all of our client – from ChatGPT users to developers to businesses who rely on OpenAI products , ” OpenAI write . “ We ’ve fall short of our own expectations . ”
