An investigation was immediately launched, with Anthropic confirming disruptions across claude.ai, the Claude API (api.anthropic.com), Claude Code, and Claude Cowork services.<\/p>\n<p class=\"wp-block-paragraph\">Recovery was staggered across model versions, according to Anthropic\u2019s official status page:<\/p>\n<ul class=\"wp-block-list\">\n<li>Opus 4.6 \u2014 recovered at 15:25 UTC<\/li>\n<li>Sonnet 4.6 \u2014 recovered at 16:23 UTC<\/li>\n<li>Opus 4.8 \u2014 recovered at 16:59 UTC<\/li>\n<li>Opus 4.7 \u2014 recovered at 17:12 UTC<\/li>\n<li>Opus 4.5 \u2014 recovered at 17:29 UTC<\/li>\n<\/ul>\n<p class=\"wp-block-paragraph\">Full service restoration was confirmed by 18:27 UTC (6:28 p.m. UTC), with Anthropic stating: \u201cSuccess rates across all models have returned to expected levels. We are continuing to monitor closely to ensure no further issues will recur.\u201d<\/p>\n<p class=\"wp-block-paragraph\">Anthropic engineers attributed the outage to infrastructure issues rather than a security breach, and as of 5:00 p.m. EDT, the company had not confirmed any customer data exposure.<\/p>\n<p class=\"wp-block-paragraph\">However, the incident echoes prior security concerns. A January 2026 GitHub advisory documented a vulnerability in Claude Code\u2019s project-load flow that allowed malicious repositories to exfiltrate Anthropic API keys.<\/p>\n<p class=\"wp-block-paragraph\">This is not an isolated event. Anthropic\u2019s Claude platform has experienced multiple outages throughout 2026, including a notable networking-related disruption in March affecting Opus 4.6 and Sonnet 4.6, and a worldwide outage in May 2026.<\/p>\n<p class=\"wp-block-paragraph\">Claude.ai currently reports 99.3% uptime over the past 30 days, though security analysts warn that an AI system\u2019s single-vendor&#8230;<\/p>\n<p><a href=\"https:\/\/cybersecuritynews.com\/anthropics-claude-services-down\/\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Anthropic&#8217;s Claude Services Down \u2014 claude.ai, Claude Code, and Cowork Affected [Updated] https:\/\/cybersecuritynews.com\/anthropics-claude-services-down\/ Publish Date:&#8230;<\/p>\n","protected":false},"author":1,"featured_media":266524,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"http:\/\/cybersecuritynews.com\/wp-content\/uploads\/2026\/06\/Anthropics-Claude-Services-Down.webp","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[20,30,57,27],"class_list":["post-266521","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cybersecurity","tag-artificial-intelligence","tag-breach","tag-security","tag-vulnerability"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/266521"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=266521"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/266521\/revisions"}],"predecessor-version":[{"id":266525,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/266521\/revisions\/266525"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/266524"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=266521"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=266521"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=266521"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
