IPv4 vs IPv6 routing behavior

I've noticed now that Spectrum Internet seems to favor Atlanta for IPv6 and Chicago for IPv4. This means about a 32% increase in routing time for IPv6 packets. Does anyone know why they route IPv6 packets differently?

    US is still pretty slow on IPv6 adoption… well, pretty much most of the world is in general.

    Even though we have finally crossed the 50% threshold here, overall adoption rate is still down around 43-45% (the numbers vary a little by source).

    Doesn't help that a lot of things needing faster responses are still relying on IPv4 connections too, so there is less pressure to optimize IPv6 pathways.

    Doesn't seem like there is enough pressure to work on the problem.

    Companies have opted for 4to6 style tunneling and CGNAT to deal with the limited v4 address pools... and seem to be fine with it, as it is working well enough to keep them profitable for now. Same with the online gaming industry... they keep getting away with relying on UDP over IPv4 and are less inclined to properly support IPv6.

    ¯\_(ツ)_/¯
