It's guaranteed to be up for a year at least, and probably much longer after that. If a major host or ibiblio wanted to guarantee its availability by hosting it permanently, I expect UBM (the parent company) would be amenable. Not right now, but perhaps at the one-year mark.
Presumably, if the content will no longer be changing, one push it out to a set of static pages and host it on a single instance in EC2, if it is clearing several hundred thousand a year in its current ad clicks that would pay a system administrator and general "minder"'s salary.
I find it particularly poignant because I recently scanned in my copies of the early compendium volumes "running lite without overbyte" which I had bought at the West Coast Computer Faire so long ago. Unwilling to keep the large format books around, they live on as searchable PDFs on my iPad.
