應該是伺服器那邊 (即網站那邊) 出問題,不是你的電腦問題。
請遲些時間,再試多幾次!!
HTTP 404
HTTP 404或Not Found錯誤訊息是HTTP的其中一種「標準回應訊息」(HTTP狀態碼),此訊息代表客戶端在瀏覽網頁時,伺服器無法正常提供訊息,或是伺服器無法回應且不知原因。 404錯誤訊息可能與「server not found」(無法找到伺服器)或其他類似訊息容易產生混淆。
概要
當客戶端使用HTTP瀏覽網頁時,伺服器需要針對不同的「要求」提供不同的「回應」,譬如瀏覽器發出HTML文件(網頁)的要求,並帶有數字回應碼和MIME的訊息。代碼404的第一個「4」代表客戶端的錯誤,如錯誤的網頁位址;後兩的數字碼則代表着特定的錯誤訊息。HTTP的三字元代碼跟早期通訊協定FTP和NNTP的代碼相當類似。
從HTTP的層面來看,404訊息碼之後通常會有一個可讀的訊息「Not Found」[1],許多網絡伺服器的預設頁面也都有「404」代碼跟「Not Found」的詞彙。
404錯誤訊息通常是在目標頁面被更動或移除之後顯現的頁面。因為此兩種訊息需要特別架構的伺服器,許多網站並不使用。
錯用的404頁面
一些網站會以「200 OK」的回應訊息來回覆「not found」的錯誤,此稱為soft 404。
