Today, I upgraded most of the software on our server.
This includes things like our web server software, database and email systems, etc.
It even includes the operating system that the server was running.
While the upgrade was performed quickly (less than an hour!), and, so far, no problems have been reported, I'd still ask everyone to keep an eye out. If you see anything broken, or acting strangely, please let me know by creating a thread in the admin stuff forum.
