HTML5 validator.w3.org

Question

My site has been valid until today, wondering if this is my site or a validator error.

I get this message:

Error found: 500 Cannot connect to localhost: 8888 (connect: Connection failed)

Answer 1

An HTTP 500 error is an internal server error, so this will be their error. Try validator.nu while you wait.

If you made any recent changes to your domain name (DNS) configuration, you may also need to check the correctness of your domain records or ask your hosting company to do this.
