Ms Meek said the current problems highlight a wider issue, where rural and island communities can become cut off from other areas due to technology failing.
She added: “We had been winding down Tiree Broadband because of fibre coming, and now we’re having to spin back up with this.
“It’s clear that fibre is not infallible, and there is no real back-up. This has raised serious questions as we are reliant on the internet to do so much now – right down to the Co-op ordering stock in.”
Neil MacPhail, the chair of the community development trust, said Tiree Broadband was having to do the work of both BT and Openreach at the moment.
He added: “The community is keeping the island connected, but without a guarantee that the data will continue to be paid for, we simply can’t extend service to everyone who needs it.”
