response. 10.1 Informational 1xx This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. There are

no required headers for this class of status code. Since HTTP/1.0 did not http status code define any 1xx status codes, servers MUST NOT send a 1xx response to an HTTP/1.0 client except under experimental http 502 conditions. A client MUST be prepared to accept one or more 1xx status responses prior to a regular response, even if the client does not expect a 100 (Continue) status message. Unexpected 1xx

status responses MAY be ignored by a user agent. Proxies MUST forward 1xx responses, unless the connection between the proxy and its client has been closed, or unless the proxy itself requested the generation of the 1xx response. (For example, if a proxy adds a "Expect: 100-continue" field when it forwards a request, then it need not forward the corresponding 100 (Continue) response(s).) 10.1.1 100

Continue The client SHOULD continue with its request. This interim response is used to inform the client that the initial part of the request has been received and has not yet been rejected by the server. The client SHOULD continue by sending the remainder of the request or, if the request has already been completed, ignore this response. The server MUST send a final response after the request has been completed. See section 8.2.3 for detailed discussion of the use and handling of this status code. 10.1.2 101 Switching Protocols The server understands and is willing to comply with the client's request, via the Upgrade message header field (section 14.42), for a change in the application protocol being used on this connection. The server will switch protocols to those defined by the response's Upgrade header field immediately after the empty line which terminates the 101 response. The protocol SHOULD be switched only when it is advantageous to do so. For example, switching to a newer version of HTTP is advantageous over older versions, and switching to a real-time, synchronous protocol might be advantageous when delivering resources that use such features. 10.2 Successful 2

Er funktioniert immer noch minimal, da er zumindest mit einem 503-Statuscode reagieren kann, aber ein vollständiger Service ist unmöglich, d.h. die Website ist einfach nicht erreichbar. Es gibt https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html unendlich viele Gründe dafür, aber im Allgemeinen treten Sie wegen irgendwelcher menschlicher Eingriffe durch die Betreiber des Webserverrechners auf. Sie können gewöhnlich damit rechnen, dass jemand an dem Problem arbeitet und der normale Service so schnell wie möglich wieder aufgenommen wird. Bitte wenden Sie sich an die Systembetreiber der Website (z.B. Ihren ISP), um festzustellen, warum der Service außer Betrieb http://www.checkupdown.com/status/E503.html ist. Diese sind in einer viel besseren Position, um Ihnen zu helfen, als wir dies bei diesem Fehlertyp sind. 503-Fehler im HTTP-Ablauf Jeder Client (z.B. Ihr Webbrowser oder unser CheckUpDown-Roboter) durchläuft den folgenden Ablauf, wenn er mit dem Webserver kommuniziert: Eine IP-Adresse aus dem IP-Namen der Site zuweisen (die URL der Site ohne das vorangestellte 'http://'). Dieses Nachschlagen (Umwandlung des IP-Namens in die IP-Adresse) wird durch Domain-Namen-Server (DNS) geleistet. Öffnen einer IP-Socket-Verbindung zu dieser IP-Adresse. Schreiben eines HTTP-Datenstroms über diesen Socket. Rückempfangen eines HTTP-Datenstroms vom Webserver als Antwort. Dieser Datenstrom enthält Statuscodes, deren Werte durch das HTTP-Protokoll bestimmt werden. Parsen dieses Datenstroms auf Statuscodes und andere nützliche Informationen. Dieser Fehler tritt im obigen letzten Schritt auf, wenn der Client einen HTTP-Statuscode empfängt, den er als '503' erkennt.

HTTP status codes are three-digit codes, and are grouped into five different classes. The class of a status code can be quickly identified by its first digit: 1xx: Informational 2xx: Success 3xx: Redirection 4xx: Client Error 5xx: Server Error This guide focuses on identifying and troubleshooting the most commonly encountered HTTP error codes, i.e. 4xx and 5xx status codes, from a system administrator's perspective. There are many situations that could cause a web server to respond to a request with a particular error code--we will cover common potential causes and solutions. Client and Server Error Overview Client errors, or HTTP status codes from 400 to 499, are the result of HTTP requests sent by a user client (i.e. a web browser or other HTTP client). Even though these types of errors are client-related, it is often useful to know which error code a user is encountering to determine if the potential issue can be fixed by server configuration. Server errors, or HTTP status codes from 500 to 599, are returned by a web server when it is aware that an error has occurred or is otherwise not able to process the request. General Troubleshooting Tips When using a web browser to test a web server, refresh the browser after making server changes Check server logs for more details about how the server is handling the requests. For example, web servers
