I am actually subscribed to dyndns, for this machine.

But I normally use openvpn, which works perfectly.
I've had a couple of occasions when openvpn has failed -
as it happened, one time was due to a storm in Italy
when the internet connection went down -
but what I have found is quite nice in the past
is that if openvpn fails I can ssh in, if I know the IP address,
and try to work out what is wrong with openvpn.

Eg openvpn stopped working for a couple of hours
when I upgraded the remote machine (as well as my local server)
to CentOS-5.4.
Strangely, it just started working again a couple of hours later.
