In a previous generation, it wasn't as redundant as what we finally released, and the hard disk in one of our machines that had everyone's email stopped working. I came in and everyone I walked past would ask me, "When is Caribou going to be back up?" I was walking into the machine room with screwdrivers, and people saw me and were like, "Oh no!"
I managed to take apart the hard drive and transplant the electronics from another drive, so nothing was lost. Through the whole thing, we've never lost any data, which is kind of unbelievable considering everything that happened.
