I don't get why IT people get so uppity about answering some fairly basic questions.
If part of the plant goes down on the shop floor, the fitter doesn't huff and puff and sigh when asked how long the plant will likely be down. He gives a rough estimate.
It's not really that hard to be polite and helpful.
(This is not aimed at anyone on here, just an observation)
Obviously this is old equipment, as now it'll be controlled by IT at the bare minimum - and until I take a look I've no idea how long it'll take to fix nor (if it needs parts), how long a supplier will take to deliver/fit the part.
