On a side note: I'm sure you're working for a company I used to work for. Are you working in an IT company?
One of my old bosses (there were two) kept complaining about the bandwidth everyone kept using and she used to rant and rave about how expensive the internet was and how inefficient and unproductive we all were. During the day she used to randomly pop into people's offices to check what they were doing, what sites they were on, and their browser history. It got so bad she and the other boss eventually started constantly monitoring everyone's computers but her own and the IT department's.
Funnily enough, they couldn't figure out where the bandwidth was going but anytime you went into her office she was on Skype, or YouTube, social media, watching a video, or leaving any of the above running while she went and screamed at someone/s in other offices.
Nope not IT, Manufacturing.
It started years ago when the company (+-30 staff on Pc's) had a very crapy and slow 4mb line, people would complain the internet is unusable and they can't do their research or whatever, they then upgraded to 2 100mb lines which kind of solved the issue until everyone started using online services for work and of course people downloading stuff and watching YouTube all at the same time soon caused the network to be slow and unresponsive sometimes.
So the big boss (who does all his work with online services) got pissed because he is paying for the speedy internet yet it's still problematic. First thing they did was add usage caps for each user 2gb per month after which you have no internet, (This wasn't in effect for management and people the boss was fond of,) when this wasn't enough they disciplined those who were abusing the net, and started monitoring usage Live so they can take action when the network becomes saturated.
The issue is 90% of us aren't misusing it, we are just going about daily business and tend to do a lot of stuff online but now we are too scared too. They also won't allow you to use your Mobile data so you don't saturate their network nor will they remove the cap if you can prove your usage was work related.
I basically only visit this forum and google a thing or two, all the files and sheets that I store online I download on my phone and transfer with USB which is incredibly annoying.
