Hitting peak performance: Why full fibre is so reliable 

Josh G | Social Media & Content Lead

More streaming, more scrolling, more screen-time... it all takes a toll. Unless you’ve got full fibre, that is.  

You know how it goes – some days you’ve got a lot more in the tank than others. And that’s totally OK, because not every day’s meant to be a personal best. But when it comes to your broadband, only peak performance will do. Enter full fibre – the sturdiest, most reliable broadband around.  

Fighting fit with full fibre  

Let’s go back to broadband basics. There are actually two main types of connection – copper cables and full fibre. Copper wires are older technology that use your phone line to bring internet into your home, making them slower and much more likely to break down. Whilst full fibre runs directly into your home using fibre optic cables – hands down the most reliable connection out there.  

At Cuckoo, we’re full fibre all the way.

Head-to-head: copper wires vs full fibre 

Back in the day, the internet wasn’t used for much more than the odd email. Those old-school copper wires were designed in the era of landlines (remember those?), so they can’t always handle the strain of today’s internet use. And that’s why you might end up with slower downloads, stuttering streams or buffering right as you’re about to share your screen in a meeting. 

 

Full fibre, on the other hand, was designed to deal with all the technology you need in modern life. Like 4K streaming, gaming, WFHing and so much more. So, when it comes to loading, it doesn’t just keep up – it races ahead. Like the reliable little speedster it is.  

Weathering the wildest days on the web 

Most days, the internet is a pretty busy place. But some days, it’s like a shopping centre on Christmas Eve. Utterly crowded and chaotic, with simple things like paying for stuff in your basket taking forever.  

During these really busy times, some broadband set-ups can’t handle the strain (copper cables, we’re looking at you) because they share a connection with a whole street or neighbourhood. And when everyone’s online at the same time, the copper cables get overloaded and give up.  

But other types of broadband (hello, full fibre) can hold strong – because every connection serves one home directly, and isn’t impacted by what other people are up to. Pretty cool, right? 

Take Black Friday as an example. On 1st December 2024, shoppers were snapping up deals while Fortnite fanatics downloaded the latest update. The result? A huge 405 petabytes of data consumed on the Openreach network (that’s enough to keep your TV streaming in 4K for over 40 million hours). And a lot of frustrated people whose connections couldn’t keep up.  

Moral of the story? Full fibre’s your key to staying online, all the time.  

How to boost your broadband connection

Hopefully now we’ve convinced you that full fibre’s ridiculously reliable. Here are a few tips and tricks to make sure you always get peak reliability: 

Plug in 🔌 – whenever you can, connect your laptop or phone to your router with an Ethernet cable. It just makes everything that little bit smoother. 

Share nicely 🤗 – got an important call? Nicely ask your Twitch-loving housemates to pause their gaming spree 

Declutter your network🧹 – check your router settings and disconnect anything you don’t use anymore (like old phones or laptops). Like a spring clean, but for Wi-Fi. 

Get an extra eero router ➕ – this helps spread the signal and coverage further in your home with a mesh system  

Let full fibre do the heavy lifting
