Hi @eric786. Welcome to GoDaddy Community! That error usually indicates that the website is trying to use more resources than what is available on the site. If this is for a WordPress site, I'd suggest trying to install a caching plugin. That is a pretty common fix for WordPress 503 errors. If it's not a WordPress site, please provide more details on the situation. Others may have additional suggestions.
I am getting the same thing. Over two dozen times I have seen this error.
Constantly losing changes.
My website and control panel is very slow as well.
I was on Windows hosting. Slow.
Changed to Linux hosting. Slow.
Changed to managed wordpress hosting. No difference!
Increase memory limit to 256M successfully. No difference!
Un-installed all un-used plugins, plugins I use are resource intensive but are used common and used by thousands with no issues. Paid for premium plugins.
Reactivated Cachify plugin. No difference!
Is this GoDaddy? Am I wasting my time and money by purchasing new hosting options?
Easily takes me 10x as long to do what I need to do, that's when I am not getting the 503 error.
