The cause of the “509 bandwidth limit exceeded” error message seems straightforward and it may be in some cases. However, it often isn’t as simple as shelling out cash for an unlimited bandwidth web hosting package. Even if does get rid of the error, the potential underlying cause can continue draining your resources, regardless of the web hosting provider or the CMS (Content Management System) in use. This leads to slower loading times, sluggish performance, and even worse, more disastrous errors with their own codes. Since time is of the essence, let’s get straight into how to fix “509 bandwidth limit exceeded” error.
1. Enable website caching
There’s no reason not to use caching on your website, no matter which CMS powers it. Many caching services are free or offer free trials, and only get more effective with payment plans. The service will analyze the PHP scripts on your website, and save them as static HTML pages. Then, when a browser sends a request to your website, your server generates and shows these static pages instead of original scripts. This not only improves loading time but also reduces bandwidth usage by up to 80%, especially when combined with CDN.
2. Utilize a CDN (Content Delivery Network)
Storing content on one server makes sense with a local website. Well, somewhat; you still have to worry about massive slowdowns or the “509 bandwidth limit exceeded” error appearing during times of peak traffic. International users will experience high latency, slow loading times, and run a higher risk of the aforementioned error. Using a CDN solves those issues by caching, then storing your website content on servers located across the world. When someone visits your website, the server closest to their location fulfills the request. Because less data needs to be transferred from the origin server, less bandwidth is consumed in the process.
3. Reduce your website’s file size
The next way to drastically cut down on bandwidth usage is to shrink the size of your entire website. It makes sense, right? Every time a visitor opens your website, their browser sends a request for the files on your web server and downloads or processes them. The larger the files are, the more bandwidth is used. Here’s how to minimize that:
Make things simpler
A website jam-packed with animations, massive images, or videos playing in the forefront or the background can look cool. But it also requires a lot of storage size and bandwidth to be shown to visitors. Look into replacing the elements of your website with simpler things that are equally effective. Also, remove as much content as possible without losing the visual appeal or desired functionality. If embedding videos is unavoidable, host them on external services. Remember, less is more sometimes.
Compress and resize images
Unnecessarily large images are the common source of large bandwidth costs. Although your CMS is smart and makes them fit, they should never be larger than the display size. If your images are already the perfect size, consider image compression. It can reduce their size by 70%-90%, depending on when the image quality deteriorates too much.
This should be automatically enabled as part of method 1, but may not be. Lazy loading will make the content on your website load only when the visitor scrolls to it. That way, their browser doesn’t need to request entire pages at first load. You eliminate bandwidth loss for people who visit, then click away, or immediately find what they need, and don’t scroll down.
4. Inquiry about hotlink protection
If the methods above didn’t help, a third party might be leeching off your bandwidth. Although frowned upon, this practice isn’t uncommon. Instead of uploading their resources, malicious webmasters embed yours. That way, the content gets displayed on their website, yet you pay the bill for the bandwidth usage their visitors create. Ask your website hosting provider to investigate and protect you accordingly.
5. Sort out your payments
Check your e-mails and sign in to your user account on the hosting’s website and look for any notifications. Verify that your payment method is still valid, that there isn’t a charge you must approve, or that there are sufficient funds. While waiting for the payment to go through, web hosting services usually throttle your bandwidth to the point of only staying online for crawlers and bots.
6. Upgrade your web hosting plan
We’ve reached the obvious way to fix “509 bandwidth limit exceeded” error – increasing the monthly bandwidth limit your web hosting service imposes. While it will cost you, look at it as a cost of success. You can always purchase an unlimited web hosting plan right off the bat, but this can be pricy. Instead, we suggest you use a web-based website bandwidth calculator tool. Or, you can do it manually, like this:
Calculate monthly bandwidth usage
The rough monthly bandwidth formula is as follows:
Bandwidth = APS × ANPV × ANDV × Days
The variables in the formula are:
- APS (Average Page Size) of your website
- ANDV (Average Number of Daily Visitors)
- ANPV (Average Number of Page Views) per visitor
- Days – days in a month; Precise (28-31) or 30 as an average
Tip. Always get more bandwidth than you need to account for unexpected traffic spikes. A recommended value is at least 50% of the calculated bandwidth.
7. Change your hosting provider
Did you expand bandwidth or opted for an unlimited one, and your website still received more traffic than the hosting server can sustain? This is a great indicator you’re using a low-quality web hosting provider. Therefore, the only method to fix the “509 bandwidth limit exceeded” error is to migrate your entire website to another web hosting service.
