JPL is usually at 300KB
Most other sites at NASA at 80K
I'll see what I can do to bump the sites all to 300.
Also I may customize the robotics.nasa.gov TV page for more choices.
Please note that broadcasting the Kickoff all depends on the Satellite TV truck getting to New Hampshire - last year the truck came from Georgia, and almost didn't make it because of a Ice storm. This year the weather looks bad on the East Coast.
Also Last year we had broadband video conferencing out of the arena, and this year we don't - just be prepared for disappointment. Working for NASA I hate advertising an event when there is a single obvious critical point of failure. No truck, no broadcast.
