Would you rephrase the part I underlined? Because I'm not sure what this "it" suggests, and what this "traveling throughout" means, I can't understand it well.

"Just about every piece of data in your organization today is considered mission-critical. And there's more of "it" than ever traveling throughout an increasingly complex and diverse IT environment."

Thank you,
'It' = data. Placing it in quotation marks is an attempt at a pun on IT (information technology).

Travelling throughout = circulating, moving, being transmitted everywhere in
Hi Mitsuwao,

I'll try to help.. Emotion: smile

In my opinion "it" refers to "every data that considered mission-critical"

but I can't suggest the meaning of "traveling throughout" maybe because of incomplete sentence, I mean the explaination maybe in the sentence before this sentence you quote..
