Guys, it looks like this is an unofficial TekSavvy (but official for other third party ISP) rule. Look at Acanac "DSL packages Overview". This is exactly what we are seeing every evening!
The problem is that TekSavvy never mentioned it. Is it a kind of fraud?
Absolutely not true. TekSavvy has no time-based restrictions on cable usage. For DSL, unlike Acanac, Teksavvy chooses to have a cap on usage from 8AM-2AM rather than a cap on rates.
