How to Fix a 503 Service Unavailable Error

Surely, when trying to visit a webpage, you’ve been met with a 503 Service Unavailable error. This error is usually server-side, and has nothing to do with your computer or your connection. However, there are a few instances when a problem on your end might be causing the 503 error to display.

In this article we’ll let you in on a few fixes you can try to make sure that the 503 Service Unavailable error is not on your end.

What’s a 503 Service Unavailable Error?

Pretty much like a 404 Not Found error, a 503 Service Unavailable error is an HTTP status code. Like the name indicates, the 503 error means that the website’s server is unavailable at the moment.

The error can occur due to an overloaded server or because the server is under maintenance.

Like every status page, the webmaster may customize the 503 error page, so it displays something different from the common “503: Service Unavailable” message.

 

The 503 error is often displayed as:

  • 503 Service Unavailable
  • 503 Service Temporarily Unavailable
  • Http/1.1 Service Unavailable
  • HTTP Server Error 503
  • Service Unavailable – DNS Failure
  • 503 Error
  • HTTP 503
  • HTTP Error 503
  • Error 503 Service Unavailable

The 503 error can be displayed under any web browser and in any operating system — that includes smartphones as well. If it’s able to go online, then it’s able to be met with a 503 Service Unavailable error.

 

Fixing a 503 Service Unavailable error

Like we’ve said, the error almost never happens due to a problem on your end. It’s a problem on the website. However, there are a few fixes which will make sure that you don’t have any problems on your end.

 

 

 

Refreshing the Page

It seems obvious, but since 503 errors are often due to an overloaded network, simply refreshing the page will fix the problem.

There are several ways to reload a webpage. You can press F5 or CTRL + R on any browser. Alternatively, you can also press the refresh icon located at the top of the page or reinsert the URL.

Even if it doesn’t fix your issue, refreshing the page will only take a couple of seconds. Worst case scenario you get the 503 Service Unavailable error again.

 

Starting a New Browser Session

It is unusual, but there’s a small chance that your browser is the cause of the error. A bug might’ve happened during your normal web browsing activities that’s making the browser assume that the site is giving a 503 error.

To fix this, or to check if this is the case, simple relaunch your browser. Close every single tab and open the browser again. If you try the website and succeed then you know that the problem was on your end — particularly on your browser.

 

Restarting Your Router / Modem

Like restarting your computer fixes lots of problems, restarting your networking equipment is the go-to fix when it comes to network problems.

 

Remember that you don’t simply want to unplug and plug back in your router or modem, you want to power cycle it. Although it seems complicated, it actually is the same as unplugging it and plugging it back in, the main difference is that you wait for a minute or so before plugging the power back on.

Again, if any of these fixes isn’t working, remember that there’s a huge probability that the problem is on the website end and not on yours. Still, if you’re able to access the website on your mobile network or on another network, there are still a few fixes for you to try.

 

Changing Your DNS Servers

503 errors can be caused by issues on your DNS servers. There are publicly available DNS addresses that you can change yours to. The most used one is Google’s.

Here’s how you change your DNS address:

  1. Open the Control Panel
  2. Choose “Network and Sharing Center” (If you can’t find it, make sure that you’re on the small icon view type)
  3. On the left side, choose “Change adapter settings”
  4. Right click on your wi-fi connection and choose “properties”
  5. Scroll down to “Internet Protocol Version 4 (TCP/IPv4)” and click on “Properties”
  6. Then, choose “Use the following DNS server addresses” and set your preferred DNS server to “8.8.8.8” and your alternate DNS address to be “8.8.4.4”. These addresses are Google’s DNS addresses
  7. Click “OK” and restart your computer

 

Check if the Website is Down for Anyone Else

To really make sure if the problem is on your end, you can simply ask someone else to try and access the website. If they can, then you definitely know that the problem is on your end.

If you don’t have anyone to ask, or you don’t have access to another computer and another network, then you can go to one of the many websites that tell you if another website is down.

If those websites tell you that the website is down, then you know that the problem is on their end.

 

Restarting Your Computer

Restarting your computer is the quintessential fix for hundreds, if not thousands, of issues. It’s something you can try out very easily and without too much trouble. Of course there’s a chance that your issue won’t be fixed, but you’ll never know until you try.

 

Clearing Your Browser’s Cache

Your browser cache can be the cause of the 503 Service Unavailable error, especially if you’ve recently visited the site and it had the error. Corrupted and outdated cache files can also be causing the issue.

Luckily, cleaning your browser’s cache takes no time at all and is very simple, although it depends on which browser you’re using.

 

Clearing Your Cache on Internet Explorer

The easiest way to clear your cache on Internet Explorer is through the Control Panel, under Internet Options.

 

 

 

 

Just head into the General Settings and click “Delete” under “Browsing History”. Even though you can delete everything from your browser, what you’re really interested in is the cache data, here known as “Temporary Internet Files and Website Files”. Just check that box and click delete.

 

Clearing Your Cache on Mozilla Firefox

Cleaning Firefox’s cache is also very simple. Just open your browser and click on the menu icon in the top right corner. From there, choose “History” and then choose “Clear Recent History”.

 

 

Then you need to select “Everything” in the time range to clear section, and you want to open the “Details” tab so you’re able to see what exactly it is that you’re deleting. You can delete everything you wish to, but what we’re really interested in here is the cache.

 

Tick the appropriate boxes and press the “Clear Now” button and your browser’s cache will be cleared.

Clearing Your Cache on Google Chrome

Open Google Chrome and its menu, located on the top right corner. Select “History” and click on “Clear browsing data…”

You want to clear data since “the beginning of time” and you want to make sure that you’ve ticked the “Cached images and files” box. You can tick whichever other boxes you’d like to delete and finally press the “Clear browsing data” button.

 

Clearing Your Cache on Safari

With Safari open, open its “preferences” window (the easiest way to do it is by pressing “CMD + ,”) and head into the “Privacy” tab.

Press the “Remove All Website Data…” button and then click on “Remove Now”.

If the problem still persists then you’ll know that it wasn’t your cache’s fault. Remember that the problem is most likely on their end.

 

Deleting Your Browser’s Cookies

If deleting your cache doesn’t work you can try clearing your cookies. It is done exactly the same way as in the previous step, but you need to mark “Cookies” for deletion.

The reason why we didn’t tell you straight away to delete your cookies, was because your cache could be to blame and because deleting your cookies will log you out of every website you’re logged into.

 

Visiting the Website at a Later Date

If none of these fixes work, then you know that the problem is on their end. If that’s the case, then there’s not much you can do other than wait.

If you really want to, and if the problem persists after a couple of days, you can try and contact the web admins directly, letting them know about the issue.

Waiting is often the only fix that works when it comes to a 503 Service Unavailable Error
