One night this month (and I can't remember exactly when) I got 404 errors
right via google, ie going to the gorups page and looking up a newsgroup,
and they'd offer a result, but if you clicked that on, it was a 404 error.
Same thing happened sometime during the past week.
I'm not even searching for something, I'm trying to access a newsgroup,
and it's like that newsgroup doesn't exist at google.
SOmetimes the simplest reasoning is that google is at fault.
