The disruption affected claude.ai, the API, Claude Code, and Cowork. Anthropic identified the cause but had not published a technical explanation or recovery time as of the latest update. This marks the fourth reported service issue in August, following incidents on the 18th, 19th, and 20th, highlighting the risk of shared infrastructure across Anthropic's growing product surface. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why is Claude showing a 529 Overloaded error right now? A 529 Overloaded error indicates a temporary server-side issue on Anthropic's infrastructure, not necessarily a client-side problem. During the 24 August incident, Anthropic reported elevated errors affecting Claude Mythos 5, Claude Fable 5, Claude Opus 5, and Claude Opus 4.8, impacting claude.ai, the API, Claude Code, and Cowork, though the company had not confirmed overload as the root cause. _Teams relying on Claude for coding workflows can track incident patterns like this via daily.dev before they hit production._ ### How many Claude outages happened in August before the 24 August incident? Three prior incidents occurred that month: a degraded-performance issue affecting multiple models on 18 August, a disruption involving Opus 5 and Haiku 4.5 on 19 August, and another multi-model disruption on 20 August. The 24 August incident affecting Mythos 5, Fable 5, Opus 5, and Opus 4.8 was the fourth reported disruption within the same month. _Anyone weighing AI provider reliability for coding tools can follow this kind of outage history through daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@shivamvyas** · 1 upvotes > claude is not reliable recently. codex is much better for daily use ## Similar posts on daily.dev -
