Posted by H9 Admin on 06 January 2015 04:33 PM

If you receive a 503 Service Unavailable error message when trying to go to your website, please review the information below. You can always contact Support via live chat regarding this issue.

What is a 503 Error?

A 503 error message indicates that there is an issue preventing access to the site but also lets visitors know that, although the service or data is temporarily not available, the target site still exists. 

Search engine rankings temporarily remain in place while a 503 error page is displayed. This gives an opportunity to address the underlying issue while maintaining search rankings. If the underlying issue is not resolved, however, search engine rankings will ultimately be affected.

A typical 503 error looks like this, though you may see a different message saying that the page cannot be found:

503 service unavailable 

Causes of a 503 Error

503 errors are specific to certain issues. Typically if you are seeing this when connecting to your HostNine site it is related to one of the issues below.

Exceeding the Processes Limit

We may need to block access to a website using more processes than allowed by our Terms of Service. This is often due to a script or plugin on your site misbehaving and using excessive resources - this can threaten the stability of the entire server.

If this is the case we will send email to the account in question. The message will include details of the issue and the steps we recommend to help resolve it.

File Permission Settings

We have permission restrictions in place for files on shared servers. This might cause the issue you are seeing (or sometimes a 403 or 500 error). Get in touch if you believe this is the issue and we can help ya out.

Password Denial, Insecure Scripts or Other Security-Related Issues

Several security issues can result in a 503 error on your site. Please review your mail for any relevant message from us regarding such an issue.
