I'm leaning towards that, too. The problem persists even when using
the provider's DNS servers. I thought for sure I'd see some verifiable
info from other people having problems with cable, such as from
dslreports, etc, but there really hasn't been anything. The comment
made about DOCSIS earlier in this thread was helpful.

Do you believe it could be impacting all data, not just bind/DNS/UDP?

Do people not generally use cable as even a fallback link for
secondary services? I figured it was because there's no SLA, not
because it doesn't work well with many protocols. I'd imagine services
like Netflix and youtube don't have problems is because they 1) don't
require a lot of DNS traffic and 2) http is a really simple protocol
and 3) the link is probably engineered to be used for that?
