500 errors from omnitrack.cinc.sh for ubuntu 22.04

https://omnitrack.cinc.sh/install.sh calls metadata URLs of this format:

https://omnitruck.cinc.sh/$channel/$project/metadata?v=$version&p=$platform&pv=$platform_version&m=$machine

We are getting 500 errors calling a URL like:

https://omnitruck.cinc.sh/stable/cinc/metadata?v=16.18.30&p=ubuntu&pv=22.04&m=x86_64

This means we can't currently install cinc on our VMs.

Any ideas when it will be back up?
