Thank you for reaching out, I’m sorry to hear about the issues that you’re experiencing with your site!

A 503 status code, or “Service Unavailable” error, means that the server is overloaded or under maintenance. If the server is not under maintenance, this can indicate that the server does not have enough CPU or memory resources to handle all of the incoming requests, or that the web server needs to be configured to allow more users, threads, or processes.

These types of issues can be troublesome to pinpoint, however we have some guides that will assist you with reviewing your Droplet’s resource usage and logs to find out what the likely causes could be:

How To Use Top, Netstat, Du, & Other Tools to Monitor Server Resources

Feel free to open the Support ticket for us to see on your Droplet. We will not be able to access it from community.

Hope this helps!
