Optus Throttling Your Internet? How a VPN Can Help

Noticing slower speeds at certain times or when streaming? You might be experiencing Optus throttling. It's more common than you think — and a VPN might be the solution.

In this guide, we'll explain what ISP throttling is, how to check if Optus is throttling your connection, and which VPNs can help restore your full speeds.

What Is ISP Throttling?

ISP throttling (also called bandwidth throttling) is when your internet provider intentionally slows down certain types of traffic. This can happen with:

• Streaming: Netflix, Stan, YouTube, and other video services
• Torrenting: P2P file sharing traffic
• Gaming: Online gaming servers and downloads
• Peak hours: General slowdowns during busy periods (typically 6-10 PM AEST)

How to Detect if Optus Is Throttling You

Here's a simple test you can do right now:

1. Run a speed test without a VPN — note your download speed
2. Connect to a VPN (any of our recommendations below)
3. Run the speed test again with the VPN active
4. Compare results: If your VPN speed is faster, your ISP is likely throttling specific traffic

You can use our speed test tool to check your connection.

Does a VPN Fix Optus Throttling?

Yes, in most cases. A VPN encrypts your traffic so Optus can't see what you're doing online. If they can't identify your traffic as streaming or torrenting, they can't selectively throttle it.

However, a VPN won't help if:

• Your overall connection is slow (congestion, not throttling)
• Optus throttles ALL traffic, not just specific types
• The issue is with your router or local network
