Well, I was VERY pleased to find tonight that all the links/URLs that I checked out were working again! I had finally gotten somebody to admit that they were moving the web servers between buildings a few weeks ago and that MAYBE that had something to do with the problems I was having. Obviously nobody briefed the distributor service staff in India about what was going on.
Now, almost all of my links point to the OLD site of rexall.com, which has been for the past few years dutifully linking over to unicitynetwork.com where the products, etc. were. During this period, it did that but then additionally went from unicitynetwork.com to unicitynetwork.ca (why it was trying to dump off onto the Candadian site, I don't know), but the DNS was screwed up for the .ca site, so all the links went from point A to point B to point C to "can't find the site"! For several weeks the only way I could even GET to any info was to go to the new unicity.net site and log in via that.
Anyway, I see that tonight unicity.net/BrendanTripp works every bit as well as rexall.com/BrendanTripp ... so I guess "all's well that ends well", although I think my hair's gotten greyer from having to try to DEAL with the process of them switching things around!
