Funny network...
I can ping the same address over my own DSL and get lower and more
stable ping than you do:

Pinging something local in my provider yields stable pingtimes within
13-14 ms...
Maybe your provider still uses old ATM technology between the subscribers
and the DSL router, and the network is heavily overbooked.
This is, however, not a generic property of DSL. DSL can have stable
roundtrip times.
