The profusehost server where most part of my sites are hosted was down for more than two days due to some maintainance works. It was the longest down time, I ever had with profusehost and its ok now. As per the administrator of Profuse Community, the downtime lasted only for a small time, and the downtime that we had was due to the DNS errors. As per the WebCEO monitoring of my site, the estimated downtime was 56h 5min 28sec. But still, I recommend profusehost for free hosting.
