Try www-fi.google.com, then -in, -va, -ab, -dc, -cw, -ex, -zu, -lm, -mc, -kr, and -sj.
For each datacentre -xx there is also a matching -xx2 version too.
The www2 and www3 addresses point to a static datacentre, often for many days or weeks at a time, and then it is suddenly changed again.
I don't know about -xx3 at all. Not tried that.
