Operating system upgrades are installed based on their severity. Patches / upgrades that fix security issues or address stability concerns are installed as soon as possible to avoid any possible threats. Generalized updates, upgrades, new versions of components and software are installed once we verify they will not negatively affect our users, servers, other applications, other services etc.
Some updates may not be installed at all or for a long period of time. For instance; just because X software went from v1 to v2, it does not mean we will upgrade to it immediately, especially if this is a website component that many users are accessing and using, upgrading to an all new version could break these web applications.
If you have any questions about our upgrade cycle please contact our sales department.
