This morning at around 5:25 A.M., Dave sent me a message that he couldn't reach my website. It was up, since I could reach it on the LAN, but when I logged into a machine a Stanford, I was not able to ping www.anderoid.com. It turned out that our IP address, which as been constant for the last couple years or so, changed yesterday around 4:30 P.M.
They agreed to provide us with a static address a couple years back. I hope it won't change again any time soon.
