More than 100,000 homes and businesses in Wales can now get access to super-fast broadband as a result of the Superfast Cymru project.
The rollout of next-generation broadband is being supported by £57 million of central government funding - added to the £58 million allocated by the Welsh Assembly - in a bid to extend coverage to 96 per cent of the country.
Ultimately, the scheme will ensure more than 690,000 Welsh properties can connect to super-fast services.
Among the communities already benefiting from a network upgrade are Blaenau Ffestiniog, Criccieth, Fairbourne, Harlech, Llanberis, Penygroes, Penrhyndeudraeth, Tywynm, Brynmawr, Clydach and Rhiwderin.
Culture Secretary Maria Miller commented that super-fast broadband "has something for everyone".
"It's brilliant news that more than 100,000 Welsh homes and businesses are already gaining real social and commercial advantages as a result of the nationwide rollout," she stated.
"The contribution that the government's delivery of super-fast broadband to 95 per cent of the UK by 2017 will make to the economic growth of the nation cannot be underestimated."
Wales Secretary David Jones said the 100,000-premises milestone marks "a significant leap forward" in the government's efforts to ensure Wales has a broadband network fit for the digital age.
