Yep. I have a 350/35 connection.
Are backbones usually heavily asymmetric? Or do the ISP's just have say, 10gbit symmetric lines that barely get used on one side, with the odd content host saturating?

Without getting into super deep detail, on cable internet, there is a balance between spectrum allocated for Tv content, and internet bandwidth. The system will have a finite amount of spectrum available, which can be divided between TV content, downstream internet, and upstream internet.
Given that most peoples usage is mostly downloading, the CATV carriers allocate more spectrum/bandwidth to downloads vs uploads.
2) The cable is a shared medium (like wifi) so it’s not just a matter of what you’re doing, but what everyone else is doing.
Finally 'full duplex' DOCSIS 3.1, renamed to 4.0, promises up to 10Gbps symmetric transfers thanks to echo cancellation (V.34 dialup modem says hi). Of course we barely switched to 3.1 and its unlikely cable networks will jump on the 4.0 bandwagon any time soon.
It's mostly about the connection from the local node to your house, not the backbone.
