I re-draft a lab test based on a algorithm rollover testbed by setting up 4
root servers with 4 different approaches of algorithm roll. More than 2
resolvers (at least bind and unbound) will be tested against each server.
This testbed will be setup this week and we kick off the rollover process
next week. If anyone who are interested to connect to this testbed, Please
reply and comment this mail. Next week I will provide the access information
of the tested in this thread.
