    99.9% uptime

    Hi
    Almost every web hosts claim they have 99.9% uptime
    How can I know they are telling the truth?
    Or generally, how can I know a web host uptime? Is there any website that show a server uptime?

    Some webhosts have a monitoring service that checks on their uptime actually. My provider guarantee a 99.5% uptime. Not the best but they maintained it above 99.89% for 2006 so far so I am pretty satistifed. I was at 99.91% for 2005.

    Down is when users can't access the websites on your server so even restarting the server is considered downtime so you can't really say that your server has not been down.

    My SHOUTcast server is rebooted every month. That gives me like 99.9% uptime. Imagine if I have undesired downtime, what will I tell to my clients? That's why I only promise to give the best possible uptime.

    Bottom line is nobody can ensure 99.9% uptime forever

    So do you have a 99.9% uptime guarantee? Some webhosts refund clients if they do not meet the guarantee. It don't even have to be the full amount, just a percentage to show the gesture.

    I use outside monitoring to show my uptime. And if we don't meet our gurantee , we do what jiehao85 mentioned, refund the percentage.

    And what if a web host dosen’t have a monitoring service
    How can check their uptime?

    How does that work - it wont let me add a host (presuming this is how I check uptime?)?

    Are you selecting the free monitoring period? I think it is now 30 minutes

    99.9% uptime = ~43 minutes of downtime each month (assuming 30 days).

    If it takes that long to reboot a server, there's something seriously wrong.

    Remember that an uptime monitor is only as good as the frequency it monitors at, there are many free services monitoring every hour (some more frequently), even a 5 min monitor will not capture most server reboots.

    The 30 min monitoring mentioned above will potentially allow the host to be down for quite some time before being recorded as down, thus still showing a high uptime even if the host has been down.

    Even a 5 min poll could easily miss sufficient downtimes to give a false uptime report.

    99.99% works out to about 5 mins/month in downtime.

    You also need to take into account scheduled downtime for OS patches, control panel updates and so on. Hosts offering 99.99% or better really need to be on fully redundant hardware, very lucky or don't update their systems

    Anything greater than 95-97% (averaged over a whole year) total uptime on a regular budget shared host is probably luck.

    99.99% excluding scheduled maintenance slots should be possible to a competent admin assuming no upstream issues.
