Where was the cannon?

Anyone know why the cannon that gets fired off in the Southwest corner wasn't at the game today?
I heard it was under going maintenance, hadn’t been cleaned in years. Might be gone for the rest of the year. Supply shortages will delay it, needs new parts.
 
The cannon guys are right in front of us, we asked & the pointed out a very large crack in the bottom base of the cannons barrel. Not safe to shoot is what they told us.

So are those guys official ISU employees who's job it is to do that?

Or just some guys who get permission to do it?

"The cannon, operated by members of the Alpha Sigma Phi fraternity, is traditionally fired after every Cyclone touchdown or field goal. Additionally, it has been fired on kickoffs and was formerly fired during the Cyclone Marching Band’s playing of the “Star Spangled Banner.”
