Web Host Uptime - How to Calculate Host Uptime Report Web Host Uptime question by Sam N : I do I determine a web host uptime and what sort of host uptime guarantees are offered by popular web hosts? Host Uptime Answer: Web Host Uptime will vary from host to host as you may already know. In the long run: the better the host uptime the more likely your website or dedicated server will be online and available for users to access. 100% uptime isn't realistic since network problems and server issues do occur. High-end managed hosting often has 5 levels, so 99.999%, but monthly costs are usually $250 and up. That said, when conducting a web hosting uptime review, the industry standard is for a 99.9% uptime guarantee. You will need to read the service-level agreement of each web host carefully if this is a concern, but in generall, most web hosts will refund (pro-rata) an amount to compensate for failing to deliver 99.9% web host uptime if they guaranteed that. We've included a list of popular web hosts with their respective uptime guarantees and the entry-level hosting plan costs to access those guarantees.
