It's unclear why anycast would be required. Most or all of their customers
use DHCP to obtain address information, including DNS information. It would
be just as reasonable for them to install a few small DNS servers
along-side the router at the cable head-end at every town. Now it might be
simpler for them to manage if they placed those same servers but used
Anycast, but the effect should be the same.
The point is, anycast is not the issue. Reliable service is the issue. DNS
isn't their only issue, of course (that they're single-homed to AT&T adds
to their unreliability, not that they can fix that at present).
