Luis,

Too bad.  I would be great if you had full OC-3 (155 Mbps) you would be
set!

I am pretty sure that the answer is yes.  After looking at the
Internet2 web site, www.internet2.edu, it seems that I2 is well
connected to the commodity internet.  Also, it seems like nearly all of
the universities that you would access for data feeds are already on
I2.  In particular, the University of Puerto Rico is already on I2
(although apparently not your campus).  Given this, your connection to
the full range of Unidata participants should be assured.  You should,
of course, directly ask the I2 representative(s) that would connect you
if there would be any way that your connection would be be limited in
any way.

The key is that Internet2 is connected to the commodity internet
through several gateways, and the great majority of Unidata
participants are already on I2.  Check
http://www.internet2.edu/html/universities.html to see the list of
universities already on I2.

Things still seem to be a lot better than they were before.  I just
pointed at your ADDE server and loaded a GOES-East image back to my
machine at Unidata in something like 2.5 seconds.

>Thank you,

It certainly sounds like things are changing for the better!
Congratulations!

Tom

Tom,

I'm already missing those other 151Mbits, it was just too good to be
true.  UPR at San Juan is already connected to I2, work over here is
underway to connect the campus to I2, that's why they were testing that
line on the internet.  I don't know how much longer it'll take, or if it
will be availiable throughout the whole campus or just to special
buildings.  I have to ask around.  Until then.
Thanks,
