[Skunkworks] KB Blogs

The above was a better, re-vamped version of KenyanBlogger.com that was created some time recently (not sure when) the former kenyanblogger site had crashed, apparently. So i happily imported my blog to this new one, KB Blogs, since back then when it crashed, all my posts disappeared. Anywho, it happened again, I guess it crashed. again, it crashed with all my posts. Basically, my question is, how exactly does a blog (hosting) website crash? And why would it happen twice to the same site?
