status.claude.com は Anthropic の公式ステータスページ — 確認済みインシデントの一次情報源です。このページは独立した、コミュニティ運営のダッシュボード(Anthropic とは無関係)。同じ公式 Statuspage フィードを読み、公式ページにない2つを足しています:リアルタイムのコミュニティ障害報告17か国からのグローバル・レイテンシ計測 — 問題がプラットフォーム全体か、地域固有か、あなただけかが分かります。公式情報は status.claude.com で確認してください。

Claude は落ちてる? — よくある質問

Claude は今ダウンしてる? expand_more

現在 Anthropic は Claude 全システム正常と報告しています。公式インシデントが出た瞬間、このページ上部のバナーが赤になります。バナーが緑なのにエラーが出るなら、たいていあなたのネットワーク・セッション・API キー側です — まず再試行を。

Claude は今どこが不調なの? expand_more

このページを上から下まで見てください:バナーが全体の信号、コンポーネント一覧がどの製品(claude.ai/Claude API/Claude Code)が影響を受けているか、右のコミュニティフィードが過去24時間に他のユーザーが報告している内容を示します。合わせて見れば、問題がプラットフォーム全体か、特定の製品だけか、あなただけかが分かります。

今日 Claude が遅いのはなぜ? expand_more

遅さは、たいてい完全な障害の前ぶれです。このページで2点を確認:レイテンシパネル(17か国からの TTFB)はあなたの地域でエッジが遅いかを、コンポーネント一覧は Anthropic が性能低下を出しているかを教えます。どちらも問題なければ、重いプロンプトや長いエージェントループがあなた側の原因の可能性が高いです。

これは Claude の Downdetector? expand_more

実質そうです。このページは Anthropic 公式 Statuspage の信号に、リアルタイムのコミュニティ障害報告とグローバルなレイテンシ計測を組み合わせています — Anthropic が確認した内容と、ユーザーがリアルタイムに報告している内容の両方が、Downdetector のように見られます。「問題を報告」ボタンで、自分の報告も追加できます。

これは公式の Claude ステータスページ? expand_more

いいえ。これは独立した、コミュニティ運営のダッシュボードで、Anthropic とは無関係です。公式ページは status.claude.com です。このページは Anthropic 公開の Statuspage データを読み、その上にコミュニティ報告とレイテンシ監視を足しています — 公式情報は必ず status.claude.com で確認してください。
