Shetland MSP Tavish Scott has called for an Ofcom investigation following a major broadband outage in the island group.
Many households and businesses have been left without broadband services for more than a week due to damage caused to Shetland's main cable link.
According to the Shetland Times, a break in the sub-sea fibre cable owned by Faroese Telecom, 61km from the island chain, has led to severe disruption.
TalkTalk and AOL subscribers are among those affected, the news provider stated.
A ship has been deployed to carry out cable repairs, and reports suggest normal broadband services will resume by the end of this week.
MSP Mr Scott believes Ofcom should investigate the service provided to customers on the isles - particularly since BT has been able to keep customers online using an alternative route to the islands.
The politician believes other broadband providers should be required to offer the same level of service, by re-routing connections to avoid the broken cable.
"It could be that the commercial broadband contract that individuals have specifies the service should be guaranteed," Mr Scott stated.
"Three companies make sure there are resilient services for Shetland. The question is, why don’t all companies selling broadband to Shetland customers do that?"
