There really is some people clueless about keeping their data centre in proper order and I really cant understand how engineers can work like this. Some of the past contracts that I worked on was a complete nightmare with having to go in disconnect everything (without folding the network) and design some type of workable plan for the data centre....good money in it though
These are out grown networks. Normally service providers grow exponentially and end up infrastructure problems like this. I think this is good opportunity for structured cabling providers
