Claude outage hits multiple models before recovery
Anthropic’s Claude service returned capacity errors across several models on August 24, 2026, then recovered without an explanation.
Anthropic’s Claude service suffered an outage on August 24, 2026, returning capacity errors for multiple models before the company marked the service operational again. Requests to Claude Fable 5 and Claude Opus 5 failed with the message: “Due to unexpected capacity constraints, Claude is unable to respond to your message. Try again soon.”
As first reported by Mashable.
The Claude status dashboard listed elevated request errors for Claude Mythos 5, Claude Fable 5, Claude Opus 5, and Claude Opus 4.8. Anthropic’s updates initially said it was investigating the problem, followed by a notice that it was continuing to address elevated errors across multiple models.

“We are investigating elevated errors on requests to Claude Mythos 5, Claude Fable 5, Claude Opus 5, and Claude Opus 4.8. We will provide an update as soon as possible.”
The service appeared to recover by 12:04 p.m. CEST on August 24, when the dashboard reported that all systems were operational. Anthropic had not disclosed the cause of the outage at that point, so it is unclear whether the capacity constraint reflected a model-serving failure, demand spike, or another infrastructure problem.
Other language-model services, including OpenAI’s ChatGPT, appeared to be operating normally during the incident. The outage’s duration and geographic scope were not established in the supplied reporting.
