----------------------------------------------------------
now:
- the 3 hour recording plays correctly from my home (and at work) using osna
servers. Rudiger says that osna is set up almost identically to usask. I can
play the media on usask servers when I am in progressive mode.

When I try to download one of the files from osna (at home) I get 173 Kb/sec

When I try to download the same file from usask I get 247 Kb/sec

A basic test pinging an ISP server in Saskatoon (non usask) from my home in
Berkeley I get 2.34 Mb/sec

The same test to Norderstedt gives me 2.64 Mb/sec

When Chris runs these same tests from the same subnet and switch as the QA
servers he the upload speed is significantly worse to Germany, but very good to
SF. I shouldn't have any problems downloading but I am.

Chris was able to watch a streaming video when he was in the same subnet as the
usask server, but he found a similar problem that I found with usask's
progressive download . There seems to be a point in time where the player is
still initializing but to the user it seems ready to go. If the player doesn't
fully load and the play button is hit the video never appears.
near future:
We need to determine whether usask has network problems that make it inadequate
as a QA environment.
- need to put a big file on one of the wobble vms
- script a cronjob to download every half an hour the file from usask, osna,
and ucb
- assess what it looks like over a day and if there is a problem with the
machine or switch it will be replaced.
