Hmmm...
http://www.lacim.uqam.ca/plouffe/Simon/articlepi.html
seems broken, but
http://www.stud.enst.fr/~bellard/pi/pi_n2/pi_n2.html
still works for me.

Or at least it was in 1997. The original decimal-digit
post-Plouffe article was:

There have been further improvements, but I haven't been
tracking them.
Over 200 billion decimal digits of Pi have been computed at
the University of Tokyo, so for most practical purposes one
can simply use table look-up!
