IT reminder.
The day before a holiday is not the day to implement major changes.
Over a holiday weekend is not the time to implement major changes.
This from someone watching non-stop e-mails about how most users cannot do any work today, and the people responsible aren't in.
Quite honestly amazed that someone just pushed a few buttons, didn't see anything explode, and called it good. Having no one test or be around in case there are issues because of a "long holiday weekend" is going to result in heads on pikes thinking.
