The first incident involved elevated errors across claude.ai, the developer console and Claude Code, and disrupted several API functions before being resolved. A second incident affected the Claude Opus 4.6 model and was fixed within minutes, with full resolution confirmed later. A third wave of errors later in the day affected the model and the main platform interface. Downdetector recorded 1,952 problem reports from US users within a 24-hour period, and some Windows users reported the desktop application failed to open. Anthropic acknowledged the issue and said it had deployed fixes for the desktop client while engineers investigated the underlying causes. The sources do not state what caused the outages.","tags":[],"date_detected":null,"near_miss":null,"root_cause":null,"root_cause_detail":null,"failure_class_detail":null,"responsible_party":null,"adversarial_actor":null,"input_provenance":null,"time_to_contain":null,"operations_paused":null,"remediation":null,"precursor_events":null},"impact":{"direct_loss_usd":null,"remediation_hours":null,"records_exposed":null,"third_parties_affected_count":null,"severity":"moderate","severity_because":"Test: moderate, data or systems of others touched with a bounded scope stated.

The article says the outage happened on Monday but gives no calendar date, so date_occurred is left out; the article's publication date (2026-03-04) is not used as date_disclosed or date_occurred. The root cause, detection method and time to contain are not stated. No risk from the closed list fits, and no control is stated as held, failed, got around or missing, so risks, links and remediations are empty; the desktop fix does not map to a listed control. Country is not stated directly (the company is described only as San Francisco-based), so it is left out. The severity tier moderate is my judgement from the bounded count of 1,952 reports, and the industry is not stated.
