3 months laterSysadmins awarded ”best performing team”
”Miracles have happened to the sysadmin team. The incident we had on yesterday was earlier something that required several phone calls and took usually hours or even a day to resolve. Typically I had to call the manager to get things moving forward.
Now I feel that it’ unnecessary to raise this kind of small things as impediments”
