So it's about 11:30 p.m. last night, I'm reading and studying at home when my computer suddenly barks that MS Outlook has lost its connection to Exchange Server (down at the office). I check my Internet connection at home (fine), then try to hit my desktop at work, then two of the servers via Remote Desktop (no joy), so either something's amiss on our server rack, the router has a problem, or the T1 (data) is down. So I think.
I call up my IT manager and we decide to meet at the office. It's midnight. When we get there, nothing appears wrong. The internal network is fine. We just can't get out. We figure it's the T1, we call Covad, and they can send an OpCenter tech right over, or, we can wait until morning for a field tech. We'll wait.
In preps for the tech the next morning, my IT manager opens the door to the central phone/data room in the building. Guess what? Someone has simply stripped the wires off the T1 jack, pulled it off the wall, and hooked it up to their phones. Turns out a new company was moving into the building last night (confirmed by the property manager). When the Covad tech comes out, he quickly confirms that the jack is hooked into the phone lines of this same company that was moving in.
Property manager calls them to confront them (they are not in their offices, 'cause I already tried to confront them myself), and they lie.
My Controller/GM is currently itemizing our losses between 8-11am when I had at least 20 of my employees twiddling their thumbs. The bill will easily exceed $5,000 and I'll be presenting it to my new neighbors as soon as I possibly can.
