What is a 5xx server error?

Instagram users have reported seeing a message displaying a 5xx server error message.

A 5xx code means the problem was cause by an issue with the server.

Typically the error occurs when the server is unable to fulfil the users request and will continue until server administration investigate the issue.

It is also important to consider that quite often, a chain of servers is handling an HTTP request, so that it may not be your server that is returning the error.
