PowWeb hosting is one of the rare shared hosting providers that offer Load Balance feature. This means if your website goes down another server will pick up its load which results in high. This is because your website is service by clusters of server, so if one server goes down, another server will pick the job. This results in very high uptime. So far we have not heard of any complaints about their service. Other then that, Powweb also offers 30 day money back guarantee so it's certainly worth a try.
