Today, Thursday, I got "Mudcat.org not found" at 8:50 a.m. Eastern STANDARD time. Came in the back door. Reading this thread, I decided to try how it is now. Exited to the Desktop, got on again, and:

At 9:15 a.m. Eastern STANDARD time, Mudcat home came up just fine.
Of course I don't know how long there had been a problem before I came on at 9:50.
