As a network engineer, I can see being involved in arguments between the server platform support teams (read: off-shore) and the network engineering teams (read: on-shore). It'll be like this; "we need network support on a call" "Hello. what's wrong?" "The entire network is down for everyone!!!!! You need to fix this!!!!! The support we get from you is horrible!!!! AAHHHHhhhhhhh!!!!!!" "OK. What changed? What was being done at the time the entire network disappeared for everyone?" "we (15 people on the call - it apparently takes that many) were doing nothing (to do nothing)." "OK, well, I'm on the cores and I can see a lot of traffic, other servers, the outside world etc. you need to define the "everything being down" part." "well, we were in the middle of doing a firmware update on server xxx01 and...." "OK, so, you lied to me about doing nothing. what did you update?" "the NIC card to improve performance for..." "And now you're wondering why the network is down..." It'll go this way for some time until the next couple of layers of management get involved....... lots of yelling, me sending pictures of the network working I should write a script for this call. I know it'll be coming.
