Once, a long time ago, I used to have a consulting gig in some big enterprise-y company. It had a lot of unique challenges, being disconnected from the internet (for security reasons, I was told) and therefore having practically everything in-house. I spent my time with not only the proto-devops-people (this was before devops was cool), but also with the hardcore sysadmins. They were in charge of the un-sexy infrastructure that kept the organization ticking. I’m talking about E-Mail, Active Directory, DNS, workstation provisioning etc. We used to joke that they were the IT equivalent of sanitation - when everything worked, no one knew you were there, toiling. When things broke, they suddenly remembered who’s responsible for this thing and where to find them. Summer was coming, and I inquired with the person in charge of WSUS (Windows Server Update Services, the Microsoft-blessed way to distribute Windows updates in offline environments) whether they’ve deployed the latest DST-related patches (the DST schedule was modified that year). They replied that no, and in fact they’d like some help in ensuring DST transitioning is disabled on all workstations/servers, as this is how things work here.
