How to manage account bandwidth in WHM?

Introduction: Bandwidth Management

Bandwidth is the total amount of data that travels between your website and its visitors. Every time someone views a page or downloads a file, it uses up some of your server’s data limit. WHM allows you to cap this usage so that your server resources remain balanced.

It is necessary to control how much data your websites transfer so that your server keeps running smoothly. You can set specific limits for each user to prevent any single site from slowing down the entire machine.

If a user hits their monthly limit, their website will stop showing until the next month starts. You can manually increase this limit at any time to keep a popular site online.

Steps to Limit Bandwidth in WHM

You can adjust the data limits for any hosting account through the account information section. This process allows you to give more resources to busy sites while restricting smaller ones.

Follow these instructions to update the monthly data allowance for a user.

  • Access your admin panel using your root or authorized reseller login.
  • Find and click the Account Information category in the side menu.
  • Select the List Accounts option to see every domain on your server.
  • Click the small + icon located next to the domain name you want to edit.
  • Press the Modify Account button that appears in the expanded area.
  • Find the Monthly Bandwidth Limit section and enter the new value in megabytes.
  • Select the Unlimited option if you do not want to cap the data usage for this site.
  • Scroll to the bottom of the page and click the Save button to apply the changes.

Frequently Asked Questions

Does the bandwidth limit reset every month?

Yes the server automatically clears the bandwidth counter on the first day of every new month. The website will start with zero usage again and become accessible if it was blocked. You do not need to reset it manually for your clients.

How often does WHM check the bandwidth usage?

The system usually checks the data totals once every twenty-four hours. It does not block a site the exact second it hits the limit. There might be a small delay before the “Bandwidth Exceeded” page appears to the visitors.

What is the difference between MB and GB in the limit box?

WHM uses megabytes for the input field so you must do a quick calculation. If you want to give a user 10GB of data, you should enter 10240 in the box. Entering a small number like 10 will limit the site to only 10 megabytes.

Can I change the bandwidth for an entire package at once?

Yes you can edit the package itself in the Edit a Package section. This change will apply to every user who is currently assigned to that specific plan. It is a faster way to update multiple accounts simultaneously.
