When your website uses more bandwidth than your hosting provider has allotted, you get the "509 Bandwidth Limit Exceeded" problem.

What Causes 509 Bandwidth Limit Exceeded Error?

Here are some common causes of the "509 Bandwidth Limit Exceeded" error:

1.  High Traffic Volume

Source

The 509 error is caused by a sudden surge of visitors that exceeds the server's bandwidth capability. This can result from viral content, promotions, or sudden interest in your website.

2.  Big File Sizes

Keeping huge media items, such as downloaded content, movies, or photos, in high definition can take up a lot of bandwidth. This can lead to the "509 Bandwidth Limit Exceeded" error, especially if multiple users are downloading these files simultaneously.

3.  Hotlinking

Without boosting your direct traffic, other websites that use your media assets have the ability to use up all of your bandwidth. This also contributes to the "509 Bandwidth Limit Exceeded" error, as it increases the load on your server.

4.  Malicious Activity

You may quickly run out of bandwidth due to DDoS attacks and other malicious traffic. For instance, spam, bots, and cyberattacks produce too much traffic to fit inside the allotted bandwidth. This not only impacts your website's performance but also leads to the "509 Bandwidth Limit Exceeded" error.

5.  Limited Hosting Plan

Having a limited hosting plan can also lead to the "509 Bandwidth Limit Exceeded" error, especially if your website experiences unexpected spikes in traffic or if you regularly exceed the allotted bandwidth limit.

Troubleshooting

Take these actions to fix the "509 Bandwidth Limit Exceeded" error:

1.  Examine Your Bandwidth Usage

To keep an eye on your bandwidth usage right now, log into your hosting control panel.
Determine usage trends and periods of high traffic to determine when and why the limit is being surpassed.

There are many solutions, such as the SolarWinds NetFlow application, that can be used to monitor bandwidth usage.

2.  Upgrade Web Hosting Package

Speak with your host to see if they can assist you in troubleshooting the problem as another option. For instance, the hosting company might provide add-ons to boost bandwidth and storage capacity.

Most of the time, your host will be able to locate the issue and assist you in solving it. It might be necessary for you to upgrade to a hosting plan with more bandwidth. In addition, when you have fixed the problem, make sure you keep a careful eye on your website to make sure the error does not recur.

3.  Compress Files

Utilize methods to minimize file sizes without sacrificing quality while compressing images and media.
Use lazy loading by loading pictures and videos only when the user's viewport is reached.
To minimize size and speed up load times, minify CSS and JavaScript files.

4.  Put Caching into Practice

Browser Caching

After a person visits your website, browser caching stores static files (including HTML, CSS, JavaScript, and pictures) on their device.

The browser loads resources from the local cache in order to minimize the time it takes to retrieve these files from the server, which leads to faster page loads.

Server-Side Caching

Server-side caching uses the server to store dynamic content, such as HTML pages or the results of database queries. The server can offer the cached version of a page rather than creating a new one when a user requests it.

Compared to dynamically generated material, cached content can be sent to consumers considerably more quickly, resulting in quicker response times.

5.  Activate the CDN (content delivery network)

With CDNs, you may spread your content over several servers globally, saving your main server's traffic.

CDNs that are widely used are Akamai and Cloudflare.

Source

To enable CDN caching with other web providers, you may need to manually add a few lines of code to the.htaccess file on your website.

Once this is done, you have to configure your CDN provider and decide which files to cache. Visitors to your website will consequently receive static files from the CDN instead of your server.

6.  Avoid Using Hotlinks and Malicious Activities

Ensure your server is configured to restrict access to unauthorized websites. Failing to do so could lead to an influx of requests for files, potentially slowing down or crashing your website. Moreover, you may end up paying for unused bandwidth due to this scenario.

Source

Depending on the server used, the ways to prevent hotlinking are different. For Apache servers, you can change the '.htaccess' file by adding a few lines of code.

Employ security services and plugins to identify and stop harmful traffic. Update your plugins, CMS, and other software frequently to fix security flaws.

It's critical to fix the "509 Bandwidth Limit Exceeded" error if you want to keep users happy and your website accessible. By comprehending the causes and implementing these troubleshooting techniques, you can successfully fix the problem and prevent it from happening again.
