No, but I do work on what is considered critical infrastructure.

Power grid?

I assume the poster is intentionally not revealing their role. While I am also curious, having known people working in the defense industry, it's considered polite to not ask questions to things they aren't offering information about.

Little known fact: sometimes the other exchanges in area code 710 will translate to places going to military bases and such, depending on the time of year. The best way to tell is by calling 710-867-5309. If you get a recording saying "You are using " followed by a not in service recording, well, it worked. If you'd care to look around random exchanges and thousand blocks, you might be in for a fun day. Or a knock at your door.

But yeah - it's all the luck of the draw. Some phone people have had varying levels of luck with other things involving that area code as well: http://www.binrev.com/forums/index.php?/topic/48478-weird-71...

When I was in college in the '80s, My roommate and I got curious about unused area codes (and/or prefixes? I forget). We started dialing some. Within about 15 minutes we stumbled on some government service with a scary-official sounding operator on the other end (I've no idea if it was this service or a different one). The really scary part was after dialing the number and encountering the operator, we were unable to…

Ah yes. The old Dormphone system that was regularly hacked/extended in various ways and reverted in a pretty much never ending tug of war.

Very interesting story, curious if you remember the number. Reminded me of my favorite scene from Community: https://youtu.be/xx_MkKJPNjQ

My recollection is we were specifically curious about what today would be called invalid address space patterns, aka numbers that were outside the patterns used in valid phone numbers at the time (such as area codes could have a 1 in the middle digit but prefixes could not have a 1 in the middle in the 1980's). We pulled out a paper phone book, devised a set of criteria for potentially interesting superficially inval…

Here's a fun one: next time you get a new phone number (USA), ask for it to end in "9999". It's possible, but not without social engineering (or influence?).

Well this is the internet, where we all have no way of sussing out subtle cultural differences between ourselves off a username. I say let the questions be asked, it causes no harm here.
