Through the 811 hotline you can call to have utility lines marked before doing any digging.

DENVER — It looks like someone may have forgotten to call before they started digging and others were unable to do so due to an outage of the Colorado 811 hotline caused by a busted fiber line.

A message on the Colorado 811 website said there was an outage in the communication system on April 21. The message went on to say that an underground fiber line was damaged and it caused" significant" outages in the Denver area.

Construction activity caused underground damage, according to the website. Crews had the damage repaired by the next morning and everything is now working again.

Colorado 811 is a nonprofit organization that was established in 1986 as the “Utility Notification Center of Colorado”. Utility owners and operators are required by law to be a member of Colorado 811 and register their underground utilities.

They don't perform location services but serve as a communication link between utility/facility owners and excavators and homeowners.

Anyone who's digging deep or even just a few inches must contact Colorado 811 to have underground utilities marked for safety.

During an outage, residents can utilize Colorado 811 online services to submit ticket requests.
