The UK's Foreign and Commonwealth Office (FCO) has rejected a request from isolated overseas territory St Helena for broadband funding.
With a population of around 4,000, the UK-owned island sits in the middle of the Atlantic Ocean between southern Africa and South America.
Residents are currently forced to rely on expensive satellite broadband for an internet connection.
The islanders are seeking £10 million in funding to access super-fast broadband, however the UK government already provides £25 million in aid per year.
And in 2011, ministers committed to build St Helena's first airport, at a cost of £200 million.
In a statement reported by the BBC, the FCO said it was aware of a plan to lay a submarine fibre-optic cable connecting South Africa and Brazil.
St Helena's government is believed to be in discussions with eFive Telecom - the firm behind the proposal - with a view to establishing a link to the island.
"If the developers proceed with the project then a full economic assessment would be needed to consider the extent of the economic and social benefits that such a link could bring to St Helena," the FCO stated.
