PXE boot enabled and attempted by default on an internet-facing network interface is certainly a... choice.
This is something that shouldn't be possible in the real world because any sysadmin should know not to do this, but guaranteed there are at least some small time operations with a couple of colo'd servers that only have single interfaces serving public traffic, and the intern who set them up didn't know what a boot order was or what "PXE" even did.
