be nice about it... ztnet although sometimes not the most reliable is at least hosting a ton of files for marp of which many should show their gratitude more than complaints... though this is quite some time for being down.
I seem to remember something like this happening once before. ZTNet went down and when it came back it messed up the scripts somehow. I think Zwaxy or someone had to do something in the end. I could be wrong though.
given the site was actually down for a couple days...they may have backed up...then restored from it.
perhaps was even just a routine total cleanup thing they do oce or twice a year.
if they restored from a backup, then permissions often get whacked....which would result in the scripts failing to run correctly.
I had a site where the host did a couple changes that resulted in this. some parts were working...others not. I had to go in and just correct the permissions again.
