You’re trying to visit a website and instead of the page you expected, you get an error message like “This site can’t be reached” or “ERR_CONNECTION_RESET.” You try another site — same thing. Now you’re wondering: is it the internet? Is it your computer? Is it something you did?
If you’re experiencing websites not loading across multiple sites, the good news is that the fix is often simpler than you think. In many cases, it has nothing to do with your computer or the websites themselves. It’s a behind-the-scenes setting called DNS — and changing it takes about two minutes.
What Is DNS and Why Does It Affect Your Web Browsing?
Think of DNS (Domain Name System) as the phone book of the internet. When you type a web address like google.com into your browser, your computer doesn’t actually know where that site lives. It needs to look up the address — just like you’d look up a phone number. DNS is the service that handles that lookup, translating the website name into a number (called an IP address) that your computer can connect to.
By default, your internet service provider (like Verizon, Comcast, or Spectrum) handles these lookups for you through their own DNS servers. The problem? ISP DNS servers aren’t always reliable. They can be slow, overloaded, or run into issues that cause pages to fail entirely. When that happens, your websites stop loading — not because the sites are down, but because your computer can’t find them.
Simple Steps to Try When Sites Won’t Load
Before jumping straight to DNS, it’s worth ruling out a few basics. Here’s a quick checklist to work through one step at a time:
Restart your router. Unplug it for about 30 seconds, then plug it back in and wait for it to fully reconnect. This clears temporary issues more often than you’d expect.
Check for a VPN or proxy. If you’re using a VPN, try turning it off. To check for a proxy on Windows, go to Settings → Network & Internet → Proxy and make sure “Use a proxy server” is turned off.
Flush your DNS cache. Your computer stores recent website lookups to speed things up, but sometimes that cache gets stale. Open Command Prompt as an administrator and type ipconfig /flushdns to clear it out.
If none of those solve the problem and you’re still seeing websites not loading, it’s time to change your DNS server.
How to Switch to a Faster, More Reliable DNS Server
Switching your DNS is one of the easiest and most impactful changes you can make. We recommend Cloudflare’s 1.1.1.1 — it’s one of the fastest DNS resolvers in the world, and it’s free. Google’s Public DNS (8.8.8.8) is another solid option.
Here’s how to make the switch on Windows:
Step 1: Open Settings → Network & Internet and click on your active connection (Wi-Fi or Ethernet).
Step 2: Find DNS server assignment and click Edit.
Step 3: Change the dropdown from Automatic to Manual.
Step 4: Turn on IPv4 and enter 1.1.1.1 as the Preferred DNS and 1.0.0.1 as the Alternate DNS.
Step 5: Click Save, then flush your DNS cache using the command mentioned above.
That’s it. Open your browser and try those problem sites again. In our experience, this resolves the issue the majority of the time — and as a bonus, your overall browsing speed may improve as well.
Why This Matters for Your Business
If you’re a business owner, websites not loading isn’t just an annoyance — it’s lost productivity. Whether you’re trying to access a vendor’s portal, check your analytics, or simply do research, connection issues eat into your day. And if your customers are experiencing similar DNS problems, your own website could be the one that won’t load for them.
This is one reason why a well-built, properly configured website matters. Speed, reliability, and accessibility all play a role in whether visitors stick around or move on to a competitor. At Insight Dezign, we build websites with performance in mind so your customers always have a smooth experience. If you’d like to learn more about how we can help, explore our digital services.
Still Having Trouble?
If you’ve tried everything above and you’re still experiencing connection issues, the problem may be deeper — a faulty network adapter, ISP-level outages, or something specific to your setup. For general network troubleshooting, Microsoft’s Wi-Fi troubleshooting guide is a good resource.
And if your business website needs attention — whether it’s loading slowly, not showing up in search results, or just due for a refresh — we’re here to help. Reach out to us and let’s talk about getting your online presence running at full speed.
