legal

How is this possible? This is as legal as traffic shaping a Point to Point T1 line. As far as I understand/know (Im a american) the pair goes into the Teksavvy or its wholesaler's DSLAM, then onto Teksavvy's ATM or SONET or MPLS lines which are rented from BC. How can BC touch the ATM/SONET/MPLS lines? Don't the five nines just get invalidated since the line isn't spiting out what when into it anymore?

It's not actually Teksavvy's ATM lines.

DSL user -> incumbent/wholesaler's DSLAM (e.g. Bell) -> Bell's ATM/ethernet/mpls/whatever network -> demarc point -> Teksavvy's 3x GbE -> Teksavvy's network

The throttling is being done within Bell's network, the question that's unknown is whether they're intentionally throttling Teksavvy clients, somehow based on protocol, or if their network is simply overloaded and throttling everyone.

AFAIK, Teksavvy has an SLO for network performance, so it's quite possible Bell is breaking that completely. As Rocky mentioned, "wait for Tuesday" when they actually have a meeting with Bell and figure out what's happening.

Personally, I'm speculating that they're throttling based on a user's usage pattern (e.g. constant max rate) because their trunk lines are overloaded, and possibly prioritizing their business clients' traffic above others.
