Reports to Downdetector about Outlook began climbing at about 17:25 UTC, 12:25 in New York. By 18:25, reports about five Microsoft services combined reached 19,650 a minute, against &lt;15 a minute on an average Thursday. <\/p>\n<p>Outlook reports alone peaked at more than 2,000 times their normal level.<\/p>\n<p>Reports did not stay in the Americas. They jumped tenfold in the UK at 17:43, in India at 23:21 local time and in New Zealand at 06:55 local time. Between 17:00 and 18:55 UTC, nearly 3 in 10 reports came from outside the US. We count a country here once its reports reach ten times normal and at least 20 in five minutes.<\/p>\n<p>Reports about Microsoft 365, Copilot, Teams and OneDrive each rose more than a hundredfold, and Azure about a hundredfold. Xbox, GitHub and LinkedIn, also Microsoft's, rose far less.<\/p>\n<p>Microsoft said a portion of its infrastructure was experiencing elevated load across multiple regions. At 19:38 UTC, reports were still running at more than 11,000 a minute.<\/p>\n<p>&mdash; Downdetector (@downdetector) <a href=\"https:\/\/x.com\/downdetector\/status\/2120981125145174504?ref_src=twsrc%5Etfw\">November 12, 2026<\/a><\/p><\/blockquote>\n<p><script async src=\"https:\/\/platform.x.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<p>\u4eca\u56de\u306e\u969c\u5bb3\u306f\u3001\u7279\u5b9a\u306e\u5730\u57df\u3084\u6a5f\u80fd\u306b\u3068\u3069\u307e\u3089\u305a\u3001\u8907\u6570\u306e\u63a5\u7d9a\u65b9\u6cd5\u3084\u30b5\u30fc\u30d3\u30b9\u3092\u307e\u305f\u3044\u3067\u767a\u751f\u3057\u3066\u3044\u307e\u3059\u3002\u516c\u5f0f\u306eMicrosoft 365 Status\u30a2\u30ab\u30a6\u30f3\u30c8(@MSFT365Status)\u306e\u767a\u8868\u306b\u3088\u308b\u3068\u3001\u30a2\u30e1\u30ea\u30ab\u5927\u9678\u306a\u3069\u306b\u304a\u3051\u308bExchange Online\u30e1\u30fc\u30eb\u30dc\u30c3\u30af\u30b9\u3078\u306e\u30a2\u30af\u30bb\u30b9\u969c\u5bb3\u306a\u3069\u304c\u78ba\u8a8d\u3055\u308c\u3066\u304a\u308a\u3001\u4e8b\u52d9\u4f5c\u696d\u3084\u30b3\u30df\u30e5\u30cb\u30b1\u30fc\u30b7\u30e7\u30f3\u30c4\u30fc\u30eb\u306b\u6df1\u523b\u306a\u9045\u5ef6\u3084\u63a5\u7d9a\u30a8\u30e9\u30fc\u304c\u751f\u3058\u3066\u3044\u307e\u3059\u3002<\/p>\n<p>\u307e\u305f\u3001Microsoft\u95a2\u9023\u306e\u30b5\u30fc\u30d3\u30b9\u3060\u3051\u3067\u306a\u304f\u3001Google\u3001Steam\u3001AWS\u3001Cloudflare\u3068\u3044\u3063\u305f\u4ed6\u793e\u306e\u4e3b\u8981\u30b5\u30fc\u30d3\u30b9\u3084\u30a4\u30f3\u30d5\u30e9\u3067\u3082\u540c\u6642\u306b\u4e0d\u5177\u5408\u304c\u5831\u544a\u3055\u308c\u3066\u304a\u308a\u3001\u5171\u901a\u306e\u30a4\u30f3\u30d5\u30e9\u3084\u5e83\u57df\u7684\u306a\u539f\u56e0\u306b\u3088\u308b\u3082\u306e\u3068\u307f\u3089\u308c\u3066\u3044\u307e\u3059\u3002<\/p>\n<h2>\u4eca\u5f8c\u306e\u898b\u901a\u3057<\/h2>\n<p>\u73fe\u6642\u70b9\u3067\u306f\u3001\u969c\u5bb3\u304c\u3044\u3064\u5b8c\u5168\u306b\u5fa9\u65e7\u3059\u308b\u306e\u304b\u3001\u3042\u308b\u3044\u306f\u6839\u672c\u7684\u306a\u539f\u56e0\u304c\u3069\u3053\u306b\u3042\u308b\u306e\u304b\u306b\u3064\u3044\u3066\u306e\u6b63\u78ba\u306a\u5168\u5bb9\u306f\u5206\u304b\u3063\u3066\u3044\u307e\u305b\u3093\u3002Microsoft\u5074\u306f\u9806\u6b21\u8abf\u67fb\u3068\u5fa9\u65e7\u4f5c\u696d\u3092\u9032\u3081\u3066\u3044\u307e\u3059\u304c\u3001\u5f71\u97ff\u304c\u5e83\u7bc4\u306b\u53ca\u3093\u3067\u3044\u308b\u305f\u3081\u3001\u30e6\u30fc\u30b6\u30fc\u3084\u4f01\u696d\u306b\u3068\u3063\u3066\u306f\u9577\u671f\u6226\u306e\u5bfe\u5fdc\u3092\u5f37\u3044\u3089\u308c\u308b\u4e00\u65e5\u3068\u306a\u308a\u305d\u3046\u3067\u3059<\/p>\n<p>[via <a href=\"https:\/\/www.windowscentral.com\/microsoft\/azure\/microsoft-365-outlook-teams-onedrive-and-copilot-are-all-down-right-now\">Windows Central<\/a>]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u8a18\u4e8b\u57f7\u7b46\u6642\u3001Microsoft\u306e\u4e3b\u8981\u306a\u30af\u30e9\u30a6\u30c9\u30b5\u30fc\u30d3\u30b9\u3084\u5404\u7a2e\u30c4\u30fc\u30eb\u306b\u5927\u898f\u6a21\u306a\u969c\u5bb3\u304c\u767a\u751f\u3057\u3066\u3044\u307e\u3059\u3002 Microsoft 365\u3092\u306f\u3058\u3081\u3001Outlook\u3001Teams\u3001OneDrive\u3001Copilot\u3068\u3044\u3063\u305f\u30b5\u30fc\u30d3\u30b9\u304c\u5e83\u7bc4\u56f2 [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":136613,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"swell_btn_cv_data":"","footnotes":""},"categories":[66],"tags":[4675,87,362,4796],"class_list":["post-136612","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-webservice","tag-copilot","tag-microsoft","tag-outlook","tag-teams"],"_links":{"self":[{"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/posts\/136612","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/comments?post=136612"}],"version-history":[{"count":0,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/posts\/136612\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/media\/136613"}],"wp:attachment":[{"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/media?parent=136612"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/categories?post=136612"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/tags?post=136612"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
