I once worked at a bourgeoning hosting provider who had one of the higher floors in a building that was condemned, but couldn't be torn down because it was home to a phone switching room that had been a part of the original 911, and the designers of technology then simply did not even imagine their systems being EOLed, so it turns out, no living or dead being knows how. I'm curious to know if that's still standing.

The freight elevator shaft had a shattered wooden freight elevator carriage at the bottom of it. We took the stairs.

Those kind of buildings are all around the country and serve various purposes - some of which specifically manage 911 calls. I can't imagine ever decommissioning one. Sometimes even gaining access takes something just shy of an act of god. While AT&T has re-consolidated in a major way, there are still a lot of external concerns to deal with.

Somebody would have to be very motivated to push through turning an interconnection point like that off. The politics involved in doing so would be extraordinary - even if there was common agreement from the start that it was time to let it go. I don't even know that you really could initiate a project like that from within a Telco.

It is a bit surprising that it was common knowledge that part of 911 ran out of there. While it's not "secret" information, the purpose and location of most similar properties are typically not openly advertised. Most people don't even know where their local CO actually is.
