Copyright notice, now my internet is throttled?

OK, so I've got some questions to see if anyone else experiences this.

I've been noticing often that my internet service simply cuts out completely, at random times.  It usually happens after receiving a (bogus) copyright infringement or excessive data usage.  The internet simply doesn't work.  I get no data transfer over my wireless router nor when I plug directly into the modem.  Yet all the lights are still green.  I then have to power cycle everything and then it starts working again, until a few hours later and the internet cuts out again.

What's the deal cox?  I think you are throttling and cutting out my service as vengeance.
