Infrastructure will look to begin OS upgrades for Ubuntu LTS releases 6 months after their release and attempt to maintain all GCP compute instances on an LTS within the last 5 years of release.

Infrastructure will look to begin OS upgrades for Ubuntu LTS releases 6 months after their release and attempt to maintain all GCP compute instances on an LTS within the last 5 years of release.
