Thousands of businesses, websites, enterprise teams and developers have been affected by a major service disruption involving Anthropic’s Claude AI platform and its third-party connectors, leaving several digital services and automated workflows temporarily unavailable.
The outage, which began earlier on Friday, has disrupted critical integrations used for email management, calendar scheduling, enterprise productivity and automated software development, raising concerns among organisations that depend on AI-powered tools for daily operations.
Key Highlights
- Major Claude AI outage disrupts websites and business operations.
- Microsoft 365 connector experiences widespread request failures.
- Claude for Outlook becomes unavailable amid Microsoft 365 service disruptions.
- Claude Code and Claude API experience partial outages.
- Claude Cowork users report degraded performance and workflow interruptions.
- AWS Bedrock, Google Cloud Vertex AI and Microsoft Foundry reportedly remain largely unaffected.
Microsoft 365 Connector and Claude Services Experience Disruptions
According to Anthropic’s official status reports, the disruption involves overlapping technical issues affecting several services.
The Microsoft 365 connector, which enables Claude to integrate with enterprise email, calendar and search applications, is reportedly failing for a significant proportion of requests.
The problem coincides with a broader Microsoft 365 service disruption, which has also affected Claude for Outlook, preventing some users from accessing AI-powered features through Microsoft’s productivity platform.
Anthropic has also confirmed significant service disruptions affecting claude.ai, alongside partial outages involving Claude Code and the core Claude API.
Claude Cowork has similarly experienced degraded performance, making it difficult for some collaborative teams to synchronise projects and execute automated tasks.
How the Claude AI Outage Is Affecting Websites and Businesses
The disruption has triggered widespread operational challenges as businesses increasingly integrate AI-powered connectors into their customer support systems, content management platforms and backend operations.
Some of the major areas affected include:
1. Customer Support and AI Chatbots
Websites that depend on Claude’s API and third-party connectors for live customer support, automated email responses and customer enquiries have reportedly experienced timeout errors and unresponsive chatbot features.
The disruption could delay customer service operations and affect businesses that rely heavily on automated communication.
2. Enterprise Productivity and Microsoft 365 Integration
Employees who depend on Claude’s Microsoft 365 integration to summarise email conversations, schedule meetings and search internal company documents have been forced to rely on manual processes.
The disruption has affected workflows that combine AI assistance with Microsoft’s enterprise productivity tools.
3. Software Development and Automated Coding
Software engineers using Claude Code for debugging, repository management, coding assistance and deployment checks have also experienced interruptions.
The disruption has slowed some development activities, including routine website maintenance, software updates and automated engineering processes.
Which Claude Services and AI Platforms Are Still Working?
Despite the widespread disruption, not all Anthropic services and infrastructure have been affected.
According to the available service updates, Claude Console and Claude for Government remain operational.
Enterprise organisations routing their AI traffic through alternative cloud infrastructure, including Amazon Web Services (AWS) Bedrock, Google Cloud Vertex AI and Microsoft Foundry, have reportedly been largely insulated from the disruption.
These alternative platforms may provide some organisations with continuity while direct Claude services and affected connectors remain unavailable.
Anthropic Investigates Outage as Businesses Seek Alternatives
Anthropic engineers are investigating elevated error rates affecting the company’s web and API infrastructure, while Microsoft is working to resolve the underlying issues affecting its Microsoft 365 ecosystem.
The overlapping disruptions highlight the growing dependence of businesses on AI platforms and third-party integrations for essential operations.

Until services are fully restored, website administrators, developers and IT teams are advised to review their automated workflows, consider temporarily disabling repeatedly failing connector triggers where necessary, and implement alternative service arrangements to minimise operational disruptions.
Businesses are also encouraged to monitor Anthropic’s and Microsoft’s official service status updates for information on recovery efforts.
The incident underscores the importance of maintaining backup APIs, alternative automation systems and reliable fallback arrangements as organisations expand their reliance on artificial intelligence.
