Here is my web site based on my visit to Morgantown a couple

For those that haven't seen the inside of one of these bunkers,
there is a link from the longlines page to my VR tour of the small L4
bunker at Finland, PA.
These pages show the inside of the AT&T bunkers at Attica and
Clarksville, NY, which are similar in size to Morgantown:
The site today serves as a fiber optic repeater and transmission
station, where circuits are patched between various long-distcance
fiber cables (now done using a digital switch called a DACS). It
may also contain a 4ESS long distance switch, or a STP/SCP
control point for controlling switches, or some other special
equipment for data or other communications networks operated by
AT&T. I don't have specific information on what is in that bunker
today, but those would be my educated guess as to its function.
See some of the maps on my maps page for more information on
what the network looked like when it was based on coax and radio.
I do not have an accurate map of current AT&T fiber routes (and
would not post such a map if I did in today's enviroment).

- Sounds like one of the many thousand data centers that have been converted
to fiber optics (FO) over the years. Nothing unusual, nothing noteworthy.
Most are remotely monitored these days. The early generator starts may be
in response to approaching storms, and lightning detectors have sensed
strikes within the area. its common practice to use backup power in
sensitive sites to pre-empt any outages. The few gallons of fuel beat any
possibility of outages, especially if site power consumption is near
battery capacity. Its far better to know the gennys are up and running
before bad weather takes the AC mains down. It could also be routine
generator running in response to timed exercise events. Are the genny
starts taking place on a timetable, like 9am mondays, every week? That
would indicate timed events. Pre-starts just before bad weather at random
times would indicate lightning detection/pre-emptive starts.
Do you have pictures?
