For the people having trouble download the podcast, I spoke with the server guy and he says, "ok, looks like there's nothing wrong with the server setup, so that is fine. I had a couple people try and download with no problem.
If possible, can you ask any user who has problems to provide: browser/os/ connection type (dsl, fiber etc), plus what time of day in what timezone - maybe we can deduce a pattern."
Please let me know.
