I could forgive un to non-, but what the hell was the logic in just removing non-? That it was like (it isn't) [in]flammable just because the 'in' isn't negating 'terruptible'?
Actually, even that doesn't make sense, you can't remove non- from non-inflammable either, that would only work if it was the 'in' removed.
This is a great question and was pretty much the last straw for me. I explained in plain english what the purpose of the UPS and battery room was, to help the PR understand why we called the thing "uninterruptible". Somehow in the final edit she confused this with "well, if the grid power can be interrupted and your servers remain on... then this means he must have meant 'interruptible' power supply.
