Website overload can lead to slow page speeds and functionality issues, frustrating visitors, causing downtime, and potentially affecting your search engine rankings. If your site starts showing errors, loading slowly, or going offline during traffic spikes, it’s essential to identify the root causes of the overload. With Domains.co.za’s Web Hosting plans, you can use cPanel’s built-in tools to help you diagnose and fix performance issues as well as monitor resource usage and find out what’s causing strain on your site.

How to Check Website Overload Causes in cPanel

Follow these steps to analyse performance bottlenecks and determine the cause of website overload using cPanel:

1. Login to your Domains.co.za account.

2. Click on Manage Services on the left-hand side and select Web Hosting from the drop-down menu.

3. Click Manage next to your website’s domain name.

4. Scroll down to the Metrics section in your dashboard.

5. Click on Resource Usage or CPU and Concurrent Connection Usage.

6. Check the report summary for any faults, such as CPU overages, exceeding memory limits, or entry process restrictions.

7. Click Details for a breakdown of usage over time, including high spikes that indicate when your site was under pressure. Use timestamps to match against site activity or traffic logs.

8. Go back and check other metric tools like:

• Errors: For 500 errors or overload-related issues.
• Awstats or Webalizer: For traffic analytics.
• Raw Access Logs: For direct visitor IPs and activity.
• Bandwidth: To spot traffic surges or large downloads.

9. This will help you evaluate what might be causing website overload, such as bots, plugins, high traffic, or large file requests

Additional Information

Common Causes of Website Overload

• Traffic Spikes: This is a primary cause, with shared hosting being particularly vulnerable. Shared hosting environments distribute resources among many users, so a sudden spike can quickly exhaust resources, leading to slow performance.
• Plugins or Themes: Bloated, inefficient, or buggy code within plugins and themes (especially on platforms like WordPress) can consume excessive server resources, resulting in slowdowns.
•  Background Processes: Cron jobs (scheduled tasks) and other background processes can tie up server resources if not optimised or if they run too frequently, negatively impacting website performance.
• Search Engine Crawlers: While search engine bots are essential for indexing your site, excessive crawling (especially by less reputable bots or if your site has a high number of pages) can put a strain on your server.
• Unoptimised Images/Scripts: Large, uncompressed images and inefficient JavaScript or CSS files significantly increase page load times, demanding more resources from the server and the user’s browser, which can contribute to overload.

How to Prevent Website Overload

Here are some tips to help prevent your website from getting overloaded:

• Optimise Database: Using phpMyAdmin allows you to identify and optimize large or slow-loading tables. You can also look for duplicate data or unnecessary entries that can be cleaned up.
• Limit Bots: The robots.txt file lets you manage how search engine crawlers and other bots interact with your site. You can use it to disallow certain bots or prevent them from crawling specific, resource-intensive areas of your site.
• Caching: Caching is one of the most effective ways to reduce server load. By storing static versions of your pages, a caching plugin (such as LiteSpeed Cache for WordPress) reduces the server’s need to generate pages from scratch for every visitor.
• Use a CDN: A Content Delivery Network (CDN) offloads static files such as images, CSS, and JavaScript to servers closer to your users. This not only speeds up your site but also reduces the bandwidth and resource strain on your main server.
• Upgrade Web Hosting: If you’ve optimised everything else and are still experiencing overload, upgrading your web hosting plan is the best solution.
