To benefit from the faster connection speeds, residents need to sign up for a fibre service with their chosen provider, as upgrades aren't automatic. More coverage is set to follow as the rollout continues.
The £410 million Digital Scotland Superfast Broadband rollout has reached another 39,000 households and businesses across Scotland in the latest three-month period.
In South Ayrshire, it means the current Digital Scotland rollout has now been completed in Prestwick, while more cabinets have also gone live extending coverage in parts of Alloway, Ayr, Kirkoswald, Prestwick and Symington.
Across Scotland, engineers have now installed more than 7,800 kilometres of new cable – enough to stretch from Loch Ness to Qinghai Lake in China.
The latest progress means more than 660,000 premises are now passed by the Digital Scotland partnership, which is led by the Scottish Government and Highlands and Islands Enterprise in their region.
BT is investing £126 million in the projects with Openreach, its local network division, delivering on the ground. Other funding partners include the UK Government through Broadband Delivery UK (BDUK), local authorities and the European Regional Development Fund.
The independent Think Broadband website shows that nearly 87 per cent of Scottish premises can now access a broadband speed of 30Mbps or above.
Fibre broadband offers fast and reliable broadband connections at speeds of up to 80Mbps* and there are many suppliers in the marketplace to choose from. It enables multiple users to connect to the internet at high speeds and get better access to online services as well as faster uploads and downloads.
The Digital Scotland Superfast Broadband programme underpins the Scottish Government's aim for Scotland to become a world class digital nation by 2020.
Cabinet Secretary for Rural Affairs and Connectivity Fergus Ewing said: "As announced in the Programme for Government, we are putting digital connectivity at the heart of our agenda and delivering 100% superfast broadband for Scotland by the end of the next Parliament is one of our priorities. Enhanced digital connectivity will improve the productivity of businesses and help to build economic growth in remote and rural areas, transforming the prospects for those who live there."
Councillor Bill Grant, Economic Development, Tourism and Leisure Portfolio Holder at South Ayrshire Council, said: "It's great news that areas such as Symington and Alloway now have access to fibre broadband thanks to the programme. The difference that fibre can make is remarkable whether you work from home or require online access through tablets, phones or computers all at the same time."
Liz Mallinson, BT Scotland's Fibre Broadband Director, added: "Every day our engineers are bringing fibre broadband to more Scottish homes and businesses. It's a massive civil engineering task which is benefiting the whole country, now and for the long term, and they're doing a fantastic job.
"The difference it makes to people from all walks of life and in all sorts of situations is amazing, whether you're running a business or have the whole family online at the same time without any slowdowns or frustrations. Whatever you do online, you can do it better and faster with fibre broadband.
"We know there's more to do. We're going to invest billions more in our high-speed broadband and mobile networks and use new technologies to boost speeds in rural areas. But with around one in four Scottish premises having made the move to a fibre service, there's plenty of capacity for many more people to benefit right now."
