By closed do you mean reactivated?

A UK article dated today discussed it being refurbished for $700 million.

Cheyenne Mountain closed last month I believe. They did a facebook live with NORAD and US Northern Command for families with questions etc.

And this is from April 7, 2020:

Northern Command troops head to Cheyenne Mountain bunker amid coronavirus fight

Excerpt:

"U.S. Northern Command troops are back in the bunker under Cheyenne Mountain as they fight a nationwide battle against coronavirus while trying to keep their distance in Colorado Springs, Gen. Terrence O’Shaughnessy said Tuesday."

"It’s the first time in 14 years the command has put the mountain into full-time use."
