I realize this is very short notice, but for those of you not aware the OpenWest conference will be hosted by UVU May 2-4 (starting tomorrow).  The cost is only $80 and looks to be a great conference.

For those troubleshooting performance or wondering how dirty networks
impact traffic, the below message link and associated info might be of
interest.

To give a feel in terms of scale, 13-15ms round trip time latency allows
you across the state of UT (north/south) on UEN's backbone.  25-30ms of
round trip latency allows you to Kansas or Houston.  50-60ms of latency
allows you to travel to/from Atlanta or New York from the UofU.  159ms of
round trip latency allows your packets to visit London and back.  160-170ms
of round trip latency will allow your packets to visit Beijing, China.
229ms of round trip latency will allow your packets to travel to Bangalore,
India and back.

Folks on this list might find this interesting:

No surprises here, but the plot shows pretty dramatically how if you are
trying to
move data more than 10ms away using TCP, you need a clean path!
