I love when we get telcos as customers for security assessments, because it means I get to see what weird old shit they have on their networks.

I find the sysadmins at telcos come in three flavours: the ones who will work with me to secure their cool old shit, the ones who want to get rid of it, and the ones who have fucking meltdowns if I consider to touch their weird old shit.

What's neat is the weird old shit usually gets support forever, whereas support for modern shit tends to be short.

I worker for a telcon for 15 years. When I left, the company was starting to add load to a new undersea cable.

Turns out most of the wet plant (a fancy way to say something is submerged under the water) were HP/UX systems.

Submarine cables must last for 20 years minimum to be financially viable... So in 2035 they will still running.

Replacing something that has worked for 25 years is a good way to end up with something that doesn't last another 25 years.
