I'm cursing my dumb ISP.
For email that I didn't see.
I suddenly found
My web site was down
From a change in my static IP.
Yesterday, my ISP suddenly changed the IP address of my web server. This means that if you tried to go to www.humbug.com, you were likely being sent to the wrong machine.
Silly me for assuming that buying a "static IP" meant my IP address would be static.
My ISP had given me a week's warning, but I rarely check the email address they sent the warning to, so I didn't see it until it was too late. It took me over six hours to notice the problem and then fix everything that needed fixing.
I apologize for any inconvenience. You may now return to your regularly scheduled humbug.
