The JTF Archive site was probably not working for people for the last few weeks. A different site of mine on the the same host was hacked and the evildoer changed a bunch of pages to serve up garbage.
Fortunately, the archiving process was not affected, so I was still gathering the show every week, just not offering it for download properly.
jtfarchive.org is now back to 100% for your listening enjoyment.
BTW, I'm serving up an average 1.5GB per day - about 48GB a month. I also see some of the accessing hosts appear to be MP3 sharing sites, so perhaps the word is spreading even further.
