What sort of chemical would this be? Unstable if heated, flash point below 73°F, extremely dangerous, don't use water? And in an alledged telecommunications hub? Maybe some sort of coolant for electronics?

Should give us a start. The sign is cumulative for all chemicals in the building so it could be more than one.

A Google search for chemicals used in telecommunications facilities turned up OSHA 1910.268(b)(2)(ii), it talks about mixing electrolyte for batteries. If there's sulfuric acid (3,0,2,W) being stored in battery cells there it could be a factor. I can't imagine they'd just have jugs of it sitting in storage though.

The rating of 2 for reactivity would have been shown. Anytime I've seen a health rating of 3, it's usually associated with benzene rings (carcinogenic). One chemical that fits a lot of the bills is Benzoyl Chloride. It eats pretty much anything that tech is made out of plastic, copper, aluminum...

I've been in a DC where there was a fairly large room completely filled with daisy chained car batteries, about 2-300 hundred in all, to provide UPS for critical servers in a power outage.
