Leland Meitzler, the owner of Heritage Creations, publishes a very popular web log (blog) called GenealogyBlog.com. That site has been offline for several days. Apparently Leland is home recovering from some minor surgery that is keeping him away from the keyboard.
During this time the site crashed or was taken offline for some reason. Leland expects to be back in full operation in about a week. In the meantime, his tech department is working on the problem as well.
I suspect that GenealogyBlog.com will be back online soon.
