I recently encountered a customer with a Dmarc and associated wiring that has me a little worried. Here is a photo of the area:

I was standing in a water when I took the photo (for some reason there are drainage issues on that side of the building). None the less, the amount of exposed wiring and the choice of location for the NIU for the customer's T1 data line are a bit frustrating. My worry is that weather (or someone with a pair of wire cutters) could do a significant amount of damage that could bring our operations down some day.

First of all, am I overreacting? I was planning on rewiring everything from the Dmarc back to the wiring closet, but I'd like to get as much of this resolved in one shot. Does anyone have any suggestions?

Thanks.
