Why is my website slow or down? Three main causes

A slow or offline website is stressful. Most problems fall into three groups. This guide helps you find which one you have.

Point 1: The server is overloaded

A server is the computer that holds your website. If it runs out of CPU (its brain power), memory or disk space, it gets slow, like a shop with too many customers.

  1. Log in to the client area at https://secure.hostvento.com/clientarea.php.
  2. Open your service and check any usage or resource notices.
  3. In cPanel, look at the resource usage page if your plan has one.
  4. Check that your disk is not full.

Fixes: remove files you do not need, clean old emails, and ask Hostvento support if you may need a bigger plan.

Point 2: The website itself is heavy

Often the site is the problem, not the server.

  • Big images: pictures of several megabytes slow every page. Shrink them before upload.
  • Too many plugins: each plugin adds work. Remove ones you do not use.
  • Old software: update WordPress, themes and plugins. Back up first.
  • No caching: caching saves a ready copy of a page so it does not rebuild each time. Use a cache plugin.
  • Old PHP version: a newer PHP is usually faster. Change it in cPanel under MultiPHP Manager, after a backup.

Point 3: Traffic, attacks or connection trouble

  • Sudden visitors: a viral post can send more people than your plan handles.
  • Bad bots: robots can hit your site again and again. Check your visitor logs for odd traffic.
  • DNS problems: DNS is the phone book that turns your site name into a number. If it is wrong, the site seems down. Check your domain settings.
  • Expired domain or hosting: look at the Domains and Services menus in the client area for expiry dates.
  • Your own internet: test the site on a phone with mobile data.

Quick checks

  1. Open the site on another device and network.
  2. Try a free speed test website to see which part is slow.
  3. Turn off the newest plugin you added.
  4. If nothing helps, open a ticket at https://secure.hostvento.com/submitticket.php. Tell support the time, the page and any error text.
Tip: Fix one thing at a time. Then you know what helped.

Quick recap

  • Cause 1: the server has too little CPU, memory or disk.
  • Cause 2: the site has big images, many plugins or old software.
  • Cause 3: traffic spikes, bots, DNS or expired services.
  • Contact support with details if you are stuck.
