I was looking for his site, and it came up "site not found". I do hope this is a temporary, technical error, not a terminal thing due to recasters, which plagued him. Anyone?
Try clearing your browser cache, too, Kylie. It may be that you got something cached, and there have been changes to his site, and now the cached content causes an error trying to reach the site.
I have been in contact with Jeff only a few days ago as I embark on a 200mm range project. He is up and running as usual.
I was very sad to hear that there has been some recasting of his fine work, when we spoke and therefore please always purchase direct from his site to make sure his artistry and authenticity remains intact.
