Anthropic is operational
IsDown pulls data from Anthropic's status page every few minutes and collects user-reported issues. Refresh the page to see if there are any updates.
This chart displays the number of user-reported issues over the past 24 hours, grouped into 20-minute intervals. It's normal to see occasional reports, which may be due to individual user issues rather than a broader problem. We only consider an issue widespread if there are multiple reports within a short timeframe.
IsDown has tracked 331 incidents since started monitoring Anthropic status in June 2024. We collect data from 4400+ services, and normalize the data to give you a clear picture of the impact of the outage.

Be the First to Know When Vendors Go Down

Services commonly monitored together with Anthropic

Anthropic is currently operational. You can check Anthropic status and incident details on the top of the page. The status is updated in almost real-time, and you can see the latest outages and issues affecting customers.

Currently there's no report of Anthropic being slow. Check on the top of the page if there are any reported problems by other users.
IsDown monitors the Anthropic official status page every few minutes. We also get reports from users like you. If there are enough reports about an outage, we'll show it on the top of the page.
Anthropic last outage was on July 21, 2025 with the title "Elevated errors on Claude 4 Sonnet"
Because IsDown is a status page aggregator, which means that we aggregate the status of multiple cloud services. You can monitor Anthropic and all the services that impact your business. Get a dashboard with the health of all services and status updates. Set up notifications via Slack, Datadog, PagerDuty, and more, when a service you monitor has issues or when maintenances are scheduled.
IsDown and DownDetector help users determine if a service is having problems. The big difference is that IsDown is a status page aggregator. IsDown monitors a service's official status page to give our customers a more reliable source of information. The integration allows us to provide more details about the outage, like incident title, description, updates, and the parts of the affected service. Additionally, users can create internal status pages and set up notifications for all their third-party services.
IsDown offers an easy way to monitor Anthropic with maximum flexibility
IsDown monitors Anthropic for major outages. A major outage is when Anthropic experiences a critical issue that severely affects one or more services/regions. When Anthropic marks an incident as a major outage, IsDown updates its internal status, the customer status page and dashboard. Depending on the customer settings, IsDown will also send notifications.
IsDown monitors Anthropic status page for minor outages. A minor outage is when Anthropic experiences a small issue affecting a small percentage of its customer's applications. An example is the performance degradation of an application. When a minor outage occurs, IsDown updates its internal status and shares that information on the customer status page. Depending on the customer settings, IsDown will also send notifications.
IsDown collects all information from the outages published in Anthropic status page to provide the most accurate information. If available, we gather the title, description, time of the outage, status, and outage updates. Another important piece of information is the affected services/regions which we use to filter the notifications that impact your business.
Anthropic publishes scheduled maintenance events on their status page. IsDown collects all the information for each event and creates a feed that people can follow to ensure they are not surprised by unexpected downtime or problems. We also send the feed in our weekly report, alerting the next maintenances that will take place.
IsDown monitors Anthropic and all their 5 components that can be affected by an outage. IsDown allows you to filter the notifications and status page alerts based on the components you care about. For example, you can choose which components or regions affect your business and filter out all other outages. This way you avoid alert fatigue in your team.
Anthropic and other vendors don’t always report outages on time. Our crowdsourced status platform helps you stay ahead of outages. Users report issues and outages, sharing details on what problems they are facing. We use that info to provide early signs of outages. This way, even without an official update, you can stay ahead of possible problems.
Very happy with isDown. Setting up and managing the monitoring is straightforward. The customer support team has been excellent, always quick to answer questions and provide assistance.
I definitely recommend IsDown.
