The 503 error can show up in a lot of ways. That means you can’t update your site in any way, and in order to troubleshoot it, you’ll need to dig into its files.

After all, not only will users be unable to visit your site, but you’ll lose access to your WordPress admin area as well. However, in those cases where the 503 error persists, you’ll have a bigger problem to deal with. Usually, this timeout is so brief that no one will notice it. WordPress very briefly sets your site to maintenance mode when you’re updating a plugin, a theme, or the core software: Maintenance mode If you’re lucky, the 503 error code will have occurred because your website is under maintenance. That’s the equivalent of calling a restaurant via phone, only to have them tell you that they’re closed but refuse to let you know when they’ll be open again. Most of the time, it just shows up with a “ Service temporarily unavailable” message. What’s so vexing about this particular error is that it barely gives you any information to go on. Unlike other similar error codes, 503 signifies that your website is online and running, but can’t be reached at the present moment. That could be because it’s too busy, for example, or it’s under maintenance. When you encounter the 503 error, it means that the server in question is unavailable. The server MAY send a Retry-After header field to suggest an appropriate amount of time for the client to wait before retrying the request. The 503 (Service Unavailable) status code indicates that the server is currently unable to handle the request due to a temporary overload or scheduled maintenance, which will likely be alleviated after some delay.
