Http ошибка 509

HTTP response status code 509 Bandwidth Limit Exceeded is an unofficial server error that is specific to Apache Web Server and cPanel that indicates that the web hosting client has exceeded the bandwidth allotment on the server-side.

Usage

When the 509 Bandwidth Limit Exceeded status code is received, it means first that the web hosting client is using a connection or hosting method where the bandwidth is limited, for example due to a fixed monthly allotment as per the web hosting contract, and that the total bandwidth allocated has been exceeded.

When this error occurs, it may warrant an investigation as to why more data is being transferred than expected. This error on the server-side can be resolved by upgrading the data allotment with the web hosting provider. This error is often temporary until the allotment resets for the next period as per the web hosting contract, however no content is accessible to users during this period.

Example

In the example, the HTTP client requests a resource using the HEAD method and the server responds with a 509 Bandwidth Limit Exceeded status code.

Request

HEAD / HTTP/1.1
Host: www.example.re

Response

HTTP/1.1 509 Bandwidth Limit Exceeded
Content-Type: text/html; charset=UTF-8
Vary: Accept-Encoding
Connection: close

Takeaway

The 509 Bandwidth Limit Exceeded status code is a server error used to indicate that the server has reached its bandwidth allowance on the server-side and consequently, the HTTP request of the HTTP client cannot be processed.

Server errors in any form can create a stir for web users for sure. However, an Error 509- Bandwidth Limit Exceeded can agitate the users as it hinders the website’s display. Website owners usually face this message when they have a limited hosting plan, i.e., a hosting plan with limited bandwidth.

With a limited number of hosting accounts, a fixed amount of bandwidth tends to be allotted every month. So, whenever the allotted bandwidth gets exhausted, the website doesn’t display anymore. With the change of month, the bandwidth value also gets reset, and web visitors can view the website again.

Error 509- What is it?

Error code 509 depicts a status code of the web server that appears on the website when it has reached the upper cap of its assigned traffic limit.

Working of Bandwidth

In the web hosting domain, the term bandwidth is used interchangeably with data transfer. As a web hosting user, one must understand the line of difference between the two.

• Bandwidth- Bandwidth is defined as the maximum amount of data that can be transferred in duration, i.e., the rate at which data gets transferred. Bandwidth is usually measured in units like kilobits/sec and megabits/sec. When we talk about fiber optics, it is measured in higher units such as gigabits/sec.

• Data Transfer- On the other hand, data transfer depicts the data volume transferred every time the website loads and is often measured in units like- megabytes, gigabytes, or even terabytes.

A website’s bandwidth gets consumed based on the traffic volume that it receives. A website having a higher traffic volume requires more bandwidth for delivering the data to its users. Upon exhaustion, website visitors incur the 509 Server Error message.

Fixing Error 509

Depending on the website type, Error 509 can be a critical concern that needs to be immediately addressed. Irrespective of whether the website is a revenue source or not, one must fix Error 509 from the perspective of SEO visibility.

Search engines can mark the website with Error 509 as ‘ínactive,’ and if the error remains for a longer duration, search engines may remove it temporarily from their search results. Any website owner never wishes such a thing to happen, so it becomes inherently important to resolve the issue at the earliest.

Website owners can get their website displayed again after the 509 Error using two approaches. The first approach could be adding to the pre-assigned bandwidth by asking the hosting provider to upgrade. In the second approach, the website owner can change to a plan that supports unlimited hosting, in the case of shared hosting.

Web hosting providers today offer unlimited bandwidth across all their shared hosting plans. It is important to note that unlimited web hosting doesn’t mean anything like having infinite resources and not being charged based on the bandwidth or disk space used.

Instead, users pay a minimal price for accessing the bandwidth and disk space that fits within the Web hosting provider’s expected usage. A small to medium-sized website without heavy traffic volume may not reach the threshold of what usually qualifies the hosting provider as unlimited.

Calculating Bandwidth

It is a challenge for any website owner to estimate his bandwidth from the beginning as he has very little clue about the traffic volume that he will receive. It is better to oversize the hosting plan when it comes to running an online business. In the case of under-sizing, it may result in the occurrence of Error 509.

One can get a rough estimate of his bandwidth by considering the following factors-

• Average page size (APS) of the website
• Estimating the average number of daily visitors (ANDV)
• Estimate the average number of page views per visitor (ANPV)
• Adding additional bandwidth for traffic surges

Once the site owner gets an estimate of the first-3 factors, bandwidth requirements can be determined using the below formulae-

This formula will just be giving a rough estimate of what one needs. Site owners must also be prepared to face traffic surges; thus, there needs to be an additional 50% ‘space,’ which can be extremely beneficial in enhanced traffic volume.

What the 509 Bandwidth Limit Exceeded Error Is

If you run into the “509 bandwidth limit exceeded” error, you’ll see a message similar to the following:

If you are getting this error, your website is using more bandwidth than your hosting plan allows. Bandwidth refers to the amount of data your site can transfer to its visitors within a set period. It’s typically measured in gigabytes (GB).

The wording of this message may also vary. For example, you may also see “storage limit exceeded” on your screen. A handful of factors can cause this scenario, which we’ll cover in the next section.

Common Causes of 509 Bandwidth Limit Exceeded

There are a few common causes of the “509 bandwidth limit exceeded” error. One of the common causes is high traffic. If your website gets a lot of traffic, it can use more resources than your hosting plan allows. This can happen if you have a popular website or referrals.

Another common cause is large files. If you have heavy files on your website, such as videos or images, they can use more bandwidth than your hosting plan allows. To fix this, you can try to optimize your website by compressing files or using smaller file sizes.

Finally, if you are on a shared hosting plan, someone else on the same server is likely using too many resources. This scenario can cause your website to use more resources than allotted by your hosting provider. If this is the case, you may need to upgrade your hosting plan.

How To Troubleshoot the 509 Bandwidth Limit Exceeded Error

To troubleshoot this error, you might need to contact your host and ask them to increase your bandwidth limit. If you’re a Kinsta user, you can use MyKinsta Analytics to troubleshoot this problem and any other issues on your site.

We also recommend calculating your bandwidth. To calculate your bandwidth, you will need to know the average size of your website’s pages and the number of visitors you get each day.

You can find out the size of your pages by using a tool such as Sitechecker’s Web Page Size Checker tool. Simply enter your URL, and you’ll receive an HTML size value:

Then, you’ll need to source information on how many visitors your website receives in a day. You can get this data from an analytics platform like Google Analytics.

If you’re a Kinsta customer, you can see this data by going to Analytics in your MyKinsta dashboard:

As you can see, Kinsta automatically calculates your bandwidth for you. Otherwise, you’ll need to multiply the number of visitors by your web page size to get your daily bandwidth usage. To calculate your monthly bandwidth usage, you can multiply your daily usage by 30.

For example, if your website is 50 MB and you get 1000 visitors per day, your monthly bandwidth usage would be 150 GB (50 MB x 1000 visitors x 30 days).

How To Fix the 509 Bandwidth Limit Exceeded Error (5 Solutions)

There are a few ways to fix the “509 bandwidth limit exceeded” error. Below are five potential solutions you can use!

1. Enable CDN Caching

Using Content Delivery Network (CDN) caching can be a great way to improve the performance of your website. It can help reduce the load time of your pages by storing static files on a CDN server and delivering them to visitors from there.

This setup can be beneficial if you have a lot of traffic. CDN caching is also handy if your website is located in a different part of the world from most of your visitors.

Some hosts include WordPress CDN services in their plans. For example, we offer Kinsta CDN, which is powered by Cloudflare.

To enable the feature, log in to your MyKinsta account. Next, navigate to Sites > Sitename > Kinsta CDN, then select Enable Kinsta CDN:

To manually enable CDN caching with other web hosts, you may need to add a few lines of code to your website’s .htaccess file. Once you have done this, you will need to configure your CDN provider and specify which files you want to cache. After that, visitors to your website will be served static files from the CDN instead of from your server.

There are a few things to keep in mind when using CDN caching. Firstly, it is essential to only cache static files. If you cache dynamic files, such as those generated by a Content Management System (CMS), they may not be updated when you make changes to your website.

Secondly, you will need to ensure that your CDN provider has enough capacity to handle the traffic to your website. If it doesn’t, your site may experience delays or downtime.

2. Avoid Hotlinking

Hotlinking is when someone includes a URL on their site that points to an image or other file on your website. This setup can cause your server to be overloaded with requests for the file, which can slow down your website or even cause it to crash. It can also result in you being charged for bandwidth that you did not use.

To prevent hotlinking on an Apache server, you can edit your .htaccess file and enable hotlink prevention. It will prevent people from hotlinking to files on your website.

Simply add the following code to the file:

RewriteEngine on

RewriteCond %{HTTP_REFERER} !^$

RewriteCond %{HTTP_REFERER} !^http(s)?://(www.)?yourdomain.com [NC]

RewriteCond %{HTTP_REFERER} !^http(s)?://(www.)?google.com [NC]

RewriteCond %{HTTP_REFERER} !^http(s)?://(www.)?bing.com [NC]

RewriteCond %{HTTP_REFERER} !^http(s)?://(www.)?yahoo.com [NC]

RewriteRule .(jpg|jpeg|png|gif|svg)$ http://dropbox.com/hotlink-placeholder.jpg [NC,R,L]

If your website runs on Nginx, you’ll want to add this code to your config file:

location ~ .(gif|png|jpeg|jpg|svg)$ {

valid_referers none blocked ~.google. ~.bing. ~.yahoo. yourdomain.com *.yourdomain.com;

if ($invalid_referer) {

return 403;

}

}

You can also contact your host and ask them to disable hotlinking for your domain. With Kinsta, you can request this service directly from your MyKinsta dashboard.

Alternatively, you can use a plugin such as All In One WP Security & Firewall:

This tool is a complete security plugin for WordPress. It helps you automatically detect and block hotlinks.

3. Optimize Your Database and File Storage

Your database and file storage can take up a lot of space on your server. If they are not optimized, they can hurt your site’s speed. Therefore, optimization should be an integral part of your WordPress website maintenance.

To optimize your database and file storage, you can compress files, use smaller file sizes, and limit the number of stored items. You can also move files to a different server or delete them altogether.

There are also plenty of database optimization plugins to choose from. A popular option is WP-Optimize:

The free tool lets you easily clean and optimize your database. It also enables you to compress your images and leverage page caching.

4. Delete Unused Files

Unused files can take up space on your server and slow down your website. To delete unused files, you can use a file manager or File Transfer Protocol (FTP) client to connect to your server and delete the files that you do not need. You should also remove any unused plugins or themes.

You can also ask your host to delete the files for you. Alternatively, you can use a plugin to detect and delete unused files automatically. An example of this type of tool is Media Cleaner:

This free plugin lets you automatically clean your Media Library by deleting any files it detects as unused.

5. Upgrade Your Hosting Plan

If you are still having trouble with your bandwidth limits, it’s best to contact your host and see if they can help you troubleshoot the issue. For example, the hosting provider may offer add-ons to increase storage space and bandwidth limits.

In most cases, your host will be able to identify the problem and help you fix it. You may need to upgrade your hosting plan to a higher bandwidth allocation. Furthermore, once you have solved the issue, be sure to monitor your website closely to ensure that the error does not return.
