It's been unavailable since before dawn last night. I found out this morning. My computer was frozen, thoroughly. Not even the manual power/reboot switch on the 'tower' worked. Walking around to the back and unplugging it did, of course, and I was back to normal in a few minutes.
The culprit this time was probably a routine malware sweep. The software I use is a 'resource hog,' and may have grabbed too much this time.
Now that I've got my other morning routines out of the way, I'll check the log of that last malware sweep. If things go well, I'll find nothing unusual.
