Undependable Fiber Link

I have a fiber connection between two IDF’s in my building. It is a 12 pair fiber run between the two IDF’s and it is run thru interducting. The cable is terminated with ST connectors into fiber patch panels. The problem is that the fiber links will go down and need to be reterminated. No one has access to the patch panels and the connections have gone down at night when no one is in the building. I am stumped on this one and any help would be appreciated.
