301 404 and 503 what is it and what do you do about it?

HTTP Status codes can be frightening to the layman when you encounter this on your website. These are simply the browser and the server talking to each other. All of these codes are broken down into 5 classes within hosting. Informational responses, successful responses, redirects, client errors and server errors.
• 100. Means everything is fine so far. The server of MijnHostingPartner.nl received it correctly and is now processing it. No further information is available yet.
• 200. The request has been received and processed correctly .
• 300. The request has been forwarded to another URL. For example with a redirect from 1 hosting to another hosting.
• 400. Something is wrong. Think 404 not found or a 403 not allowed.
• 500. Indicates that the request has been received and processed but the server cannot give you access to it.
If you get a 100 or 200 message at your website then there is nothing wrong. If you have linked to your website via the control panel or your files then you can expect a 300 code. This can also mean that a file has been moved.

serious message is a 410 message. This refers to a blocked page due to violations of a legally defined reason. Think of a censored page or material that violates copyright law.

503is

a message that pops up when the server is under maintenance or is overloaded. With Shared hosting you have the chance that another customer is causing this. This is often due to too many requests to the database or an outdated WordPress version. When you see this message you can create a ticket to the helpdesk. Always check the maintenance announcements first.
