i'm a classicaly trained IT guy, I still call them "Layer 8 issue"
I don't work on networking but I'll be adopting this from now on. https://en.wikipedia.org/wiki/Layer_8
The good old ID-10-T error
Unfortunately some users are just about bright enough to work that one out.
For those I just attach a note about it being an "IOT Error" in their report. Internet of Things is not, after all, that much different than a Internet of Tools.
I just say the problem is between keyboard and chair.
Oh yes, good old PEBKaC
Layer 0 is design.
…
Layer 8 is policy.
Layer 9 is user.
No, user and (derivatives of) have always unofficially, jokingly been layer 8. Also higher layers would refer to design issues (budget/politics/design - 9/10), not layer 0.

¯\_(ツ)_/¯ I’ve always referred to my designs as layer 0, everything is built upon them.
