I've lived here for about two months and have been very impressed with Road
Runner's cable internet service.  I called them up at 7pm to schedule an
install date and had it setup by 10am the next morning.  I didn't even have
my computers setup when they installed it.

The upstream is 40k/sec, which is plenty for hosting some small websites and
mailing lists.  The IP address is static, assuming you never the change MAC
address of the ethernet interface connected to the modem.

I run a mail server and web server, but only for testing / development
purposes.  They haven't complained yet.  If you are worried about it, pay
the extra for their commercial service.  We have one at work with a 1mbit
upstream.  That's two-thirds the speed of a T1.

Some people mentioned blocking Road Runner from port scanning you.  I do
that.  However, dropping the packets is bad, because it makes it obvious
that you are filtering them.  A better way to do it is to reject them
normally so that it looks like all of your ports are closed:

iptables -A INPUT -s 24.30.199.0/24 -p tcp \
  -j REJECT --reject-with tcp-reset
iptables -A INPUT -s 24.30.217.0/24 -p tcp \
  -j REJECT --reject-with tcp-reset
iptables -A INPUT -s 24.30.218.0/24 -p tcp \
  -j REJECT --reject-with tcp-reset
