How many times did Claude go down in March 2026?

Claude experienced four significant outages in March 2026: March 2, March 11, March 25, and March 27. The March 2 outage was tied to demand surges from the QuitGPT movement, while later outages affected Opus 4.6 and Sonnet 4.6 models specifically.

Does Anthropic offer a service level agreement (SLA) for Claude?

No public SLA exists for Claude as of March 2026. Anthropic, OpenAI, and Perplexity all require enterprise customers to negotiate SLAs individually. This absence sparked significant discussion about enterprise AI reliability.

What should enterprises do when Claude goes down?

Enterprise AI resilience best practices include implementing multi-model fallback layers with LiteLLM, adding circuit breakers and retry logic, and designing model-agnostic prompt adapters that can route to Gemini or GPT-5 when primary service degrades.

Why did Claude have so many outages in March 2026?

Anthropic attributed the March 2 outage to unprecedented demand following explosive user growth from the QuitGPT movement. Later outages in March were attributed to internal infrastructure issues as the company scaled rapidly.

Product Idea from this Signal

A distributed runtime that replaces the OpenClaw Conductor bottleneck with a peer-to-peer agent mesh that scales horizontally

42.6k ▲

Enterprise teams running OpenClaw hit a wall the moment they need more than a handful of concurrent agents. The Conductor Agent is a single point of contention that serializes all task routing, turning what should be parallel execution into a queue. With 500K+ OpenClaw instances deployed and companies like NVIDIA, Cisco, and AWS building enterprise wrappers around it, nobody has solved the core scaling problem. This tool replaces the Conductor with a distributed mesh of lightweight coordinators that shard work by project scope, letting enterprises run hundreds of agents without a central chokepoint.
