That page has a list of hostnames/sites to test downloads from.
In terms of changing dcs. Log a ticket for the admins and they will configure migration for you..
Basicly a button will appear in your panel that says MIGRATE. You click it, and it shuts your linode down, and movies it to your new host.
Apart from the reconfiguring your IP's.. Its all automagical
Hope this helps.
Cheers
NF
