Your hosting plan (Shared, VPS, or Dedicated) comes with certain limits:
| Resource | What It Means |
|---|---|
| CPU | The speed your server can process requests |
| RAM | The memory used to run websites and scripts |
| Bandwidth | How much traffic your site can handle monthly |
| Disk Space | How much storage you get for files/emails |
| IO (Input/Output) | How fast data moves between disk and app |
Visit your control panel:
Enter your credentials to log in.
In the left sidebar, click “Statistics”
You’ll see:
Disk space usage
Traffic (bandwidth)
Sometimes, CPU and RAM usage (depends on hosting)
If you’re on a shared hosting plan, detailed CPU/RAM info may only be visible from your hosting provider’s main client portal, not inside Plesk.
Website is slow or showing timeout errors
You see “508 Resource Limit Reached” or “503 Service Unavailable”
Emails stop sending or bounce back
You’re unable to upload files or receive new emails
If you’re outgrowing your current plan, you can upgrade. Here’s what to do:
Example platforms:
Namecheap: my.namecheap.com
GoDaddy: my.godaddy.com
Your host’s customer portal
Find the hosting plan linked to your domain
Click Upgrade or Change Plan
| Current Plan | Upgrade To | Why |
|---|---|---|
| Shared Hosting | VPS Hosting | You get your own resources (RAM, CPU) |
| VPS (Basic) | VPS (High-Performance) | More memory, CPU, and disk speed |
| VPS | Dedicated Server | Full control and maximum performance |
Some hosts offer automatic alerts or dashboards showing:
When RAM/CPU hits 80% or higher
When you’re nearing bandwidth or disk space limits
If available in your plan, turn on these alerts so you know when it’s time to upgrade — before your site slows down.
