Since last night, when trying to validate a few different HTML5 pages, I always get the following error at the bottom: External Checker not available Checking the Document Type of this document requires the help of an external tool which was either not enabled in this validator, or is currently unavailable. Check in the validator's system configuration that HTML5 Validator is enabled and functional. The error encountered was: 500 Can't connect to localhost:8888 (connect: Connection refused) Example URL with the error: http://validator.w3.org/check?uri=http%3A%2F%2Fblog.fligtar.com
The HTML5 backend on the validator occasionally gets taken down and needs to be restarted. It could be that it was down when you tried. If you try again and find that you're having the same problem, please re-open this bug.
The HTML5 validator seems to be down again; would you folks be willing to restart it? Thanks! Paul
