• Our lab runs 6 days a week and everything needs to be available from very early morning until late in the evening. We usually do SQL Server patching on Sundays. Networking will do OS patching Saturday evenings or Sunday evening depending on their workload. They will alternate between non-production systems one week and production the following week. This gives them a little extra time to look for any gotchas before the updates hit production. There is a little more latitude for releasing application updates since the users of the main applications are finished by 8:00pm. We still usually do them on the weekend.
