Client Website Is Down, website 404 error or 500

In the event a website hosted by net diatom goes down we will usually create an alert for all future failures to alert our team immediately.  

Notify the supervisor or management team at 800-707-7820. Also send a down site alert to contact@netdiatom.com 

Check the site again and refresh the page, also clear all cookies and try an alternative browser.

Log in h panel and force purge all cookies and browser stored data. 

If the site remains down and check the whois.net of the domain. Check the domain is currently registered. 

Make sure you are connecting to the correct url name. Check to see if an SSL certificate  Is making an issue with DNS to https or forced http redirects. 

Also check the file directory on the server to be sure you can locate an index html page in the public html directory for that site.
