Same problem for me. I saw it first on a
Radio 4 listen again page, but also see it on other BBC sites like the
BBC Weather page mentioned previously. The cable modem box crashes reliably on those pages, and is fine on other pages.
I can confirm that this only happens when I connect to the cable modem with a 10 Mbps NIC. It's fine with a 100 Mbps NIC (compared 10Mbps router and PC NIC in 10 and 100 Mbps mode).
I have an old SB4100i and 1 Mbps service.
