99.9% uptime

[Faithless]

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?

[jiehao85]

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.

i use a uptime script so visitors can see the uptime of the server, i restart the server every 2 weeks to keep it running or mine has not been down ;)

[jiehao85]

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

[jiehao85]

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.

jiehao85, what provider do you get services from?

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

[oOD-richOo]

https://www.uppanel.com/ it is an uptime tracker for your website

[Volt.Networks]

I suppose you can't check their uptime then...

https://www.uppanel.com/ it is an uptime tracker for your website

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

Yes - the button wont light up no matter what I do.

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.

[monaghan]

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.

I'm use www.siteuptimes.com & www.internetseer.com

My host uptime ~99,5%

How can I know they are telling the truth?The only way you can know with 100% certainty is to monitor one of their servers yourself. :)

The only way you can know with 100% certainty is to monitor one of their servers yourself. :)Actually, he would have to monitor all their servers (or at least a statistically significant number).

.

95% uptime over an entire year means 18 days of downtime. That is unacceptable to me at least.

I'd say 99.5% averaged over an entire year should really be the minimum (that equates to 2 days of downtime in a year). It can be certainly achieved with good planning and pro-activeness

[JodoHost]

Actually, he would have to monitor all their servers (or at least a statistically significant number).

If you are monitoring a single server for just 30 days, then you are absolutely right it would mean little or nothing to give you an actual measure of the hosts reliability. Being able to monitor more than 1 server (as many as you can) is important.

if you are monitoring a single server over a one-year period, I'd consider that an accurate estimate of reliability by that host, for that particular service. Most downtime factors tend to take place in a 1 year period, giving a better idea of how prepared a host is
