YouTube 用户(users)经常会在大约一两个小时内面临 500内部服务器错误问题，这会阻止他们访问自己喜欢的视频。(Internal Server Error)事实上，用户(users)对此错误感到非常恼火，以至于他们开始以每分钟两条推文的速度发布有关此问题的推文，所有人都在询问此 500 Internal Server Error，仅此而已。
YouTube可能会不时面临问题……这些天来，其中主要是盗版案件。一些专家说，这个错误发生过一次，因为YouTube试图实施一些新的安全功能来阻止盗版和其他对该网站的威胁。这些更改可能包括阻止用户下载视频、删除受版权保护的内容等。因此，这可能会导致服务器停机，从而导致 500 Internal Server Error。
YouTube 500 内部服务器错误
惹恼YouTube用户的 500内部服务器错误(Internal Server Error)是一种一般响应错误，仅当服务器抛出的任何请求无法找到其正确路径或无法执行特定任务或根本原因时才会发生无法识别问题。
有关 500 内部服务器错误的更多信息：
The Web server (running the Web Site) encountered an unexpected condition that prevented it from fulfilling the request by the client (e.g. your Web browser) for access to the requested URL.
这是由Web(Web)服务器生成的“包罗万象”的错误。基本上(Basically)出现了问题，但服务器在响应客户端时无法更具体地说明错误情况。除了将 500 错误通知回客户端之外，Web服务器还应该生成某种内部错误日志，以提供有关问题的更多详细信息。由Web服务器站点的操作员来定位和分析这些日志。
HTTP 周期中的 500 错误：
任何客户端（例如您的Web浏览器）在与(Web)Web服务器通信时都会经历以下循环：
- (Obtain)从站点的 IP 名称（不带前导“http://”的站点URL ）获取IP 地址。这种查找（IP 名称到 IP 地址的转换）由域名服务器 ( DNS(DNSs) ) 提供。
- 打开到该 IP 地址的 IP 套接字连接。
- (Write)通过该套接字(HTTP)写入HTTP数据流。
- 接收来自(Receive)Web服务器的HTTP数据流作为响应。此数据流包含状态代码，其值由HTTP协议确定。解析此数据流以获取状态代码和其他有用信息。
当客户端收到它识别为“500”的HTTP状态代码时，会在上述最后一步中发生此错误。
修复 500 个内部服务器错误：
此错误只能通过修复Web服务器软件来解决。这不是客户端问题。由Web服务器站点的操作员来定位和分析应该提供有关错误的更多信息的日志。
5xx 服务器错误列表：
- 500 Internal Server Error：一般错误消息，当没有更具体的消息适合时给出。
- 501 Not Implemented：服务器要么无法识别请求方法，要么无法完成请求。
- 502 Bad Gateway : 服务器作为网关或代理，从上游服务器接收到无效响应。
- 503 Service Unavailable：服务器当前不可用（因为过载或停机维护）。通常，这是一种临时状态。
- 504 Gateway Timeout：服务器作为网关或代理，没有及时收到上游服务器的请求。
- 505 HTTP Version Not Supported：服务器不支持请求中使用的HTTP协议版本。
- 506 Variant Also Negotiates ( RFC 2295 )：请求的透明内容协商，导致循环引用。
- 507 存储空间不足 ( WebDAV ) ( RFC 4918 )
- 509 Bandwidth Limit Exceeded ( Apache bw/limited extension)：这个状态码虽然被许多服务器使用，但在任何RFC(RFCs)中都没有指定。
- 510 未扩展(Extended)( RFC 2774 )：服务器需要对请求进行进一步扩展才能完成它。
- 530 用户访问被拒绝。

500 Internal Server Error on YouTube explained
Frequently, YouTube users face 500 Internal Server Error problem for about an hour and or two, which stop them from accessing their favorite videos. In fact, users get so annoyed by this error that they started tweeting about this at a rate of two tweets in a minute, all are asking about this 500 Internal Server Error, nothing else.
YouTube may face problems from time to time … these days and major among them being the case of piracy. Some experts are saying that this error occurred once because YouTube was trying to implement some new security features to stop piracy and other threats to the site. These changes might include stopping the users from downloading the videos, removal of copy-righted stuff, etc. So, this could cause the server the downtime resulting in a 500 Internal Server Error.
YouTube 500 Internal Server Error
The 500 Internal Server Error which annoys YouTube users is a general response error which occurs only when any request thrown off the server is not being able to find its right path or not being able to perform, the particular task or when the root cause for the problem cannot be identified.
Some more info on 500 internal server error:
The Web server (running the Web Site) encountered an unexpected condition that prevented it from fulfilling the request by the client (e.g. your Web browser) for access to the requested URL.
This is a ‘catch-all’ error generated by the Web server. Basically something has gone wrong, but the server can not be more specific about the error condition in its response to the client. In addition to the 500 error notified back to the client, the Web server should generate some kind of internal error log which gives more details of what went wrong. It is up to the operators of the Web server site to locate and analyze these logs.
500 errors in the HTTP cycle:
Any client (e.g. your Web browser) goes through the following cycle when it communicates with the Web server:
- Obtain an IP address from the IP name of the site (the site URL without the leading ‘http://’). This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs).
- Open an IP socket connection to that IP address.
- Write an HTTP data stream through that socket.
- Receive an HTTP data stream back from the Web server in response. This data stream contains status codes whose values are determined by the HTTP protocol. Parse this data stream for status codes and other useful information.
This error occurs in the final step above when the client receives an HTTP status code that it recognizes as ‘500’.
Fixing 500 internal server errors:
This error can only be resolved by fixes to the Web server software. It is not a client-side problem. It is up to the operators of the Web server site to locate and analyze the logs which should give further information about the error.
List of 5xx server errors:
- 500 Internal Server Error: A generic error message, given when no more specific message is suitable.
- 501 Not Implemented: The server either does not recognize the request method, or it lacks the ability to fulfill the request.
- 502 Bad Gateway: The server was acting as a gateway or proxy and received an invalid response from the upstream server.
- 503 Service Unavailable: The server is currently unavailable (because it is overloaded or down for maintenance). Generally, this is a temporary state.
- 504 Gateway Timeout: The server was acting as a gateway or proxy and did not receive a timely request from the upstream server.
- 505 HTTP Version Not Supported: The server does not support the HTTP protocol version used in the request.
- 506 Variant Also Negotiates (RFC 2295): Transparent content negotiation for the request, results in a circular reference.
- 507 Insufficient Storage (WebDAV) (RFC 4918)
- 509 Bandwidth Limit Exceeded (Apache bw/limited extension): This status code, while used by many servers, is not specified in any RFCs.
- 510 Not Extended (RFC 2774): Further extensions to the request are required for the server to fulfill it.
- 530 User access denied.
