Broadband consumers in London suffered an outage on Monday morning after thieves stole crucial networking equipment.
Entanet UK subscribers were affected by internet downtime after the raid on BT's Stepney Green telephone exchange.
Internet services went down at around 01:00 GMT, and remained down until around 16:00, with a police investigation hampering network repair works, reports ISPreview.co.uk.
Speaking to the news provider, Darren Farnden, Head of Marketing at Entanet, said engineers had been dispatched to the location as soon as the firm realised there had been an incident.
"Detailed inspection determined that several items of Entanet equipment needed to be replaced or repaired in order to restore service to customers," he explained.
"While this was Entanet's primary objective, we understandably needed to await authorisation from police attending the crime scene to proceed."
Mr Farnden suggested that other broadband providers' equipment may have been damaged during the theft.
The Stepney Green telephone exchange serves around 16,000 households and several hundred small businesses.
