I think you guys know better than me, but I'll try to summarize here:


 * rack space and power for 3 x 1U servers.

 * 4 public IP addresses

 * If possible. global IPv6 addresses should be routed as well
   (otherwise we'll use 6to4)

 * Isolated gigabit LAN to interconnect the machines.
   (this could be done with port management in the switch or
   with a small dedicated switch).

 * Contacts of on-site sysadmins who could assist us in case of
   emergencies (best-effort, no obligation).

 * Provide physical access to Sugar Labs sysadmins for initial
   setup and future maintenance. The initial setup will be carried
   on by Stefan "dogi" Unterhauser.

 * Bandwidth usage is projected to peak at 15-20Mbit/s during
   morning hours (GMT+3).

 * We don't need space for backups as these servers won't store
   valuable data and are easy to reconstruct from scratch


If RIT agrees to host it, at a later time we might add one more 1U or 2U
server running our primary websites: wiki.sugarlabs.org,
planet.sugarlabs.org, lists.sugarlabs.org and others. It's expected to
use less bandwidth than ASLO, though.

Thanks,
