Crosswinds, which has hosted my site since I first set it up, has
become increasingly unreliable of late. Crosswinds, I hope your
RAID gets better soon.
If you normally access my site via http://www.rodsladen.cjb.net,
as recommended, the move should be transparent. That's the whole
point of using a redirection service - I can recommend cjb.net. If you access my site
directly at its old location, you will just have to wait until
Crosswinds recovers, or until a search engine finds the site
again for you.
