I'm waiting on a build to finish, playing a little bit of WorldOfGoo, and I notice that my Sun Ray is no longer connected to the server. Strange.

I've also lost connection to the other server in my data closet. Now, I know the battery on the UPS back there is almost dead, a brownout the other day caused a reboot. I go and check and they are okay.

I look at my Rosewill 8-Port Gigabit Switch and wonder if I loosened something when I connected my MacBook Air to it earlier that night. Nope, but then I wonder why only half the links seem active. I confirm my data closet punches into one of the silent links. I try moving it, but I don't have anything labeled, so who knows how well that is going to work.

I happen to have a spare Rosewill sitting there (good deal at NewEgg.com a couple of years ago), so I swap it in. And sure enough, the data closet is back.

I think the old Rosewill had been going of late. I'd noticed some strange hangs to web sites on one of my machines and not the other.

I'm still happy with the units - I've got another servicing another data closet. And the one that failed had been on for probably 18 months straight.
