# Claude is Down : Anthropic Scrambles to Fix The Global Outage

Anthropic identified the cause of elevated errors hitting Claude Mythos 5, Claude Fable 5, Claude Opus 5 and Claude Opus 4.8 on August 24, 2026, and said a fix is underway. It had flagged the errors on its status page just after 5 a.m. UTC.

## Key Takeaways

- Anthropic identified the cause of elevated errors across four Claude models and says a fix is in progress.
- Claude Mythos 5, Claude Fable 5, Claude Opus 5 and Claude Opus 4.8 are the models named in the update.
- The status moved from Investigating to Identified in 21 minutes, between 5:06 a.m. and 5:27 a.m. UTC.
- Anthropic’s status page has logged 11 other incidents since August 12.

## What We Know?

Anthropic titled the incident “**Elevated errors for multiple models**” on its [status page](https://status.claude.com/incidents/vgz5psbjmt1h). At **5:27 a.m. UTC**, the company said it had “**identified the cause of elevated errors on requests to Claude Mythos 5, Claude Fable 5, Claude Opus 5, and other Claude models and are working on a fix**.” An earlier update, posted at 5:06 a.m. UTC, had named Claude Opus 4.8 among the affected models too.

On X, the account Downdetector posted that user reports of Claude AI problems began around 1:08 a.m. EDT, tagged #ClaudeAiDown, a timestamp that lines up closely with when Anthropic’s own investigation began.

 ## What We Don’t Know?

Anthropic hasn’t said what caused the errors or when a fix will ship. The company also hasn’t detailed how many requests failed, or whether claude.ai, the **Claude API**, **Claude Code** and **Cowork** saw the same error rates. As of this writing, the incident remained open at the Identified stage.

## SQ Magazine’s Takeaway

Four models failing in that same short window points to a shared dependency, maybe a routing layer or a shared inference cluster, rather than a bug in one model’s weights. That’s harder to route around than a single model failure, especially as [Claude usage](https://sqmagazine.co.uk/claude-ai-statistics/) grows across more products.

Teams running production traffic on any of the four named models should check Claude Status Page before retrying failed requests, since hammering a still degraded backend just adds load.

Anthropic hasn’t given a timeline for a fix, and this incident adds to a status page that has looked unusually busy for most of August.

Definition of AI Inference. Link to full glossary entry follows the description.**AI Inference**AI inference is the execution phase where a trained AI model applies what it learned to new, unseen data and produces an output such as a prediction.
