The team sort-of functions. But they're stuck in a form of groupthink, where they seem to prefer building their own tools/scripts, our server monitoring is poor/non-existent (only application logs), they are very reluctant to move to AWS, security obsessed to the point of manually setting routes and firewalls manually, very poor automation overall etc etc But because they dominate our devops/infra, it's very hard to penetrate the groupthink, our CTO is thankfully getting involved.
