Looking more and more like a case of incompetence. MSNBC is reporting Lieberman's website was hosted on a server with 70 other sites, which were also having problems.

Sounds like he was using a low-end hosting plan, probably had a bandwidth cap. And they had all their eggs in one basket (server): email, webhosting and ftp.

Still, what a chintzy stunt to blame his opponent. I'd be firing a few people. Pronto.
