The copper telephone network that has carried UK calls for over a century closes on 31 January 2027. Most coverage focuses on desk phones. The bigger risk is everything else running quietly on those same lines, from lift alarms to door entry panels.
What happens to your business when the internet goes down?
There was a time when a broadband fault was an inconvenience. Email stopped, people got on with something else and it came back by lunchtime.
That is no longer how it works. As phone systems move onto the internet ahead of the copper network closing in January 2027, the broadband line stops being one service among several and becomes the thing everything else depends on.
What actually stops
Picture a Tuesday morning where the line goes down and nobody can tell you when it will be back.
The phones stop, because they run over the internet now. Card payments stop. Teams calls drop and the meeting cannot be rearranged because the calendar is in the cloud. Files are unreachable. The booking system is unreachable. Staff working from home cannot get to anything either, so sending people home does not help.
Every one of those used to fail separately. Now they fail together, because they all travel down the same line.
Why one connection is no longer enough
The usual objection is that outages are rare. They are, until they are not, and the cause is very often nothing to do with your provider. A contractor puts a digger through a duct. A cabinet is damaged. A fault takes three days to find.
The question is not whether it will happen. It is how long you can trade without it.
For a business where the phones are the front door, the answer is usually hours rather than days. That is what makes a second connection worth having.
What a backup connection looks like
There are three common approaches, and the right one depends on the site.
A mobile failover connection uses 4G or 5G to carry traffic when the main line drops. It is the most common choice, it is inexpensive, and where the mobile signal is decent it is more than enough to keep phones and card payments running.
A second fixed line from a different provider gives more capacity but only helps if it takes a genuinely different route into the building. Two lines in the same duct fail together.
Satellite broadband has changed considerably in the last few years. It no longer means slow speeds and long delays, and it does not depend on any cable running to your premises at all, which is precisely what makes it useful as a backup.
When satellite makes sense
It comes into its own where the ground based options are thin.
Rural sites in Northumberland and County Durham where fibre has not arrived and the mobile signal is patchy. Farms and estates. Veterinary practices with branch surgeries in villages. Holiday parks. Manufacturing sites on the edge of an industrial estate where the last stretch of cable was never upgraded. Temporary sites and construction offices that need a connection before anyone will dig a trench.
In several of these cases satellite is not the backup. It is the main connection, with a mobile link behind it.
How the switchover works
Done properly, staff should not need to do anything. The equipment detects the main line failing and moves traffic across automatically, usually within seconds. Calls in progress may drop, but the next one connects.
Done badly, someone has to find a cable and swap it over, which means it happens twenty minutes late and only if the right person is in the building.
The difference is in how the network is set up rather than in what you buy, which is why we handle it as part of cloud managed networking and monitor both connections rather than just the one you are using.
Worth asking now
If your phones have already moved onto the internet, or they are about to, this is the right moment to ask what happens when the line drops.
We survey sites across the North East and give you a straight answer about what would stop, how long it would stop for and what it would cost to fix that. Some businesses decide the risk is acceptable. That is a reasonable conclusion to reach on purpose rather than by accident. Get in touch or call us on 0191 296 0111.
