Comcast customers in Denver were in the dark Saturday morning after someone cut a fiber optic cable line.
Comcast spokeswoman Cindy Parsons said Comcast started having trouble at the Denver hub at 6:45 a.m., which impacted the greater Denver Metro area.
Many customers got a blank screen with the text "We've detected an interruption in your service" and a customer service hotline number. Others saw a frozen image.
Parsons estimated the number of people affected to be in the hundreds of thousands.
Service was restored at the 7NEWS studios around 10:30 a.m. Parsons said customers in the metro area would see service return in waves.
Internet and phone connections were not affected by the blackout.
Facebook and Twitter were full of comments from angry viewers hoping to see Saturday football.
Comcast is the largest cable operator, home Internet service provider, and third largest home telephone service provider in the United States.
