Academy boxes do not work

For the Stack Based Buffer Overflows on X86 module, the machines that you can spawn and SSH into do not work for me. If I use the VPN or Parrot OS Pwnbox, when I ping the machine I may get 6 packets back before all packets time out and are dropped. If I try to SSH, usually I am not able to get to the password prompt before the machine times out. I tried refreshing the instance and trying new instances with different IPs, same result. Is no one else experiencing this?
