How to Fix WordPress 503 Service Temporarily Unavailable Error

HTTP Error is a kind of an http status code error. It is also called ‘service unavailable’ as it indicates that the web server you are attempting to reach is currently inaccessible. This error is widespread among the users of the WordPress platform.

The error may arise due to a number of factors. We are going to examine these factors in the proceeding conversations. We are also going to look into how to tackle each of these factors in order to fix this particular error.

Common Causes Of 503 Errors In A WordPress website. 

System Overload

Chances are that at the time you are accessing the server, it is handling way too many requests. It could also be under some maintenance. If either of these two is the case, then the system may often get overwhelmed to the extent of not being available to any user. If this is the case, the system will often generate this service unavailable error message.

Limited Server Space

If your hosting account has exhausted all the available resources, this error will most definitely arise. This kind of issue is most prevalent on shared hosting platforms as each user is assigned a specific quota. It is hence necessary to keep checking whether the quota is still sufficient to ward off the likelihood of this issue arising.

Overwhelmed Google XML sitemap plugin

Most WordPress sites usually have the Google XML sitemap plugin attached to it. This plug-in plays the role of keeping an accurate track of the various pages that jointly make up a website. It is not uncommon for this plug-in to be overwhelmed with posts. When this happens, the site slows down and subsequently generates the said error.

Unreachable External Server

WordPress does communicate extensively with external servers. From time to time, the external servers may often go down or become unavailable for several reasons. This issue also has a hand in the emergence of this particular error code.

Inaccessible Database

Lastly, the error may also be brought about by an inaccessible database. This is because the WordPress Database manager plugin is designed to optimize large databases periodically and automatically. Sometimes the databases may be inaccessible for a limited duration of time and for various reasons. If this error occurs, the scripts may not be accessible and with it, the emergence of this error.

1: Reload the page

This is perhaps the simplest and the most convenient approach to the issue altogether. Simply reload the page you are trying to access. To do this, just press ‘F5’ on your keyboard. You may copy the address, post it afresh on the address bar of your web browser, and hit ‘enter’ as an alternative attempt. Depending on the exact page you are reloading, you might have to re-enter some information you had entered before.

2: Power cycle your router and modem

This is perhaps the simplest and the most convenient approach to the issue altogether. Simply reload the page you are trying to access. To do this, just press ‘F5’ on your keyboard. You may copy the address, post it afresh on the address bar of your web browser, and hit ‘enter’ as an alternative attempt. Depending on the exact page you are reloading, you might have to re-enter some information you had entered before.

In case the intervention above yield no fruit, you may consider powering your router and modem. This is because the problem might never be with the WordPress per se, but with the network connectivity as a whole.

The Domain Name Server (DNS server) in particular may often have DNS server configuration issues which have a bearing on the functioning of the site as a whole. By restarting these two devices, you will be in a position to rectify such issues. To do this, follow the procedures outlined below:

Step I: Shut your computer, then your modem, and finally your router, in that order

Step II: Unplug the power cables from both the modem and the router

Step III: Wait for some time

Step IV: Plug in the power cables back

Step V: Switch on both the router and the modem. Hold on until they are fully powered on.

Step VI: Switch on your computer and check to see whether the HTTP Error 503 has finally been resolved.

3: Try Later

In most cases, this issue persists for a limited duration of time i.e. the server is temporarily unable to execute the incoming requests. This is why it may always be a wise idea to just wait and try your luck again later. After a meaningful duration of time, you may consider paying a visit to the site a second time. Chances are that the server is fully maintained, or that some visitors have already left.

4: Ask for Help

Lastly, you may need to seek help from a qualified and trained expert in the field or the respective website owners. To do this, log on to your WordPress page and access the administration panel in the site section. Thereafter, check the server load and ask for the external support from then on.
