Someone probably opened up a browser on a server to look something up and then left it running. With a static IP and battery backup, only a reboot is likely to take it down. The connection should be able to survive short outages due to a firewall restart or momentary problem upstream, especially if there's no NAT in between. I'm using SSH's ControlMaster in persistent mode on my desktop at work. The connections stay open for as long as the desktop is up, which can be months at a time.
