Technically it's not one page. Most likely the other pages were "cached" and you made the new request for that, and the browser couldn't resolve the IP, even though it "knew" it from the other pages.
I was able to reload the scripts, even visit my site... but I had not run the nph-index.cgi script before (in the past 12 hours) so it wasn't cached in any way.
The only reason I say this, is that I hit the same problems, repeatably, every night. The first few months it was extremly frustrating, since the pattern was more variable, and I couldn't sense it. Now, I just take a break and come back, it's all ok within the hour. But this 12 midnight to 1am window seems to be much more consistent in the past 2-3 months.
Everything is working for me this morning. As if nothing had been wrong in the first place.
