Ah. Well, might have spoken too soon. The redirect seems to be back, at least when I use my tablet. I decided to redirect my subdomain library.customerservicezone.com to customerservicezone./db in .htaccess, and it does the redirect thing, even though no files in the subdomain should be accessed.
Go figure. I still think there's something odd going on at the hostnexus end.
