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.

No user has ever encountered a 500 themselves, nor have visitors ever reported one. But they do show up in the logs. Most of the time, the error is in connection with a bot request (decent bots too, including googlebot, bingbot). All User-Agents that do not seem to be a bot include the Linux string. The only common thread I can infer across all these 500s is the bot/linux UAs connection.
