retired machines

can I do practice on retired machines??

Quoting from the What is VIP? section:

VIP Subscription Benefits
  * Less crowded labs
  * Lab access to all Retired machines (20 per week)
  * Access to official writeups for Retired machines
  * Switching between US/EU lab servers
  * Separate rankings including Retired machines
  * Unlimited resets

I have vip account but I can not access most of the machines. I can not ping Mischief, Secnotes and several other machines.

use the ticket system cos we dont know exactly what happens. it’s the better way to fix the problem.
