Web Hosting Talk : Web Hosting Main Forums : Web Hosting : The Uptime paradox:

[Nestle]

I am monitoring several hosts. One of them is the $10/year host called discount-hosting.com, some others include the very reputable here Splashhost and Voxtreme.
I am monitoring DH and Splashhost since November of 2001, and Voxtreme since September 2002.

The results:
Splashhost: 98.78% (last downtime about 10 days ago)
Voxtreme: 99.78% (last downtime about 4 days
Discount-hosting: 99.94% (last downtime about 84 days ago)

Now I am not comparing DH with the other hosts in support or feutures, since the other 2 hosts are much better in that. But how can DH have such a good uptime while other more reputable hosts can't?

What are you using to monitor?

It checks every 15 minutes.

Greetings:

1. If you want more accurate results, monitor ever minute. DH could be down 13 or 14 minutes out of every 15, and you would still report it up if you hit it right.

2. Some providers have their own sites on a server totally separate from their customers.

This can lead to very different statistics.

Thank you.

At such a length of time, I'd think it shows fairly accurate results. No way to be for certain, though.

In the same respect as possibly being down for 14 minutes out of every 15... they could also be down for 59 seconds out of every 60.

Matt

About 2, maybe. Is there any way to check that?

About 1, i don't think so. If i monitor every minute sure i will get more accurate results. E.g the 99.94% could be 99.97% or 99.90%, but i don't think it could be 99.8% or less. They can't be THAT lucky, right?

Greetings:

Ask eBay how they might feel about 14 minutes of down time. A lot can happen in 15-minuets; and comparing that to what can happen in 60 seconds is not apples to apples.

As to #2, ask them for client sites and contact information. Then you can verify over the phone, as well as monitor.

Also check out http://uptime.netcraft.com/up/graph/...nt-hosting.com and http://uptime.netcraft.com/up/hosted...80.247.227.255

Thank you.

Just..want to know

I use internetseer.

Unless your monitoring service is checking every second, the uptime percentages should be considered estimating the average(mean) thru samples. Over several months, whether it's checking every minute or hourly, you are likely to get very close to the same result -- sample size is not linear -- doubling the sample size will not cut the confidence interval in half.

I run a script similar to nagios on my monitoring server. The name is slipping me, i'll edit this post when I remember.

Heres the edit: npulse http://www.horsburgh.com/h_npulse.html

[Wulex]

what is nagios ?

[alapo]

www.nagios.org A very nice FREE script you can run. Only downside... it takes HOURS to config (no, I am not kidding).

Edit: er oh, and sorry for taking this thread off topic, I wont be making any more except that edit I promised .

[Wulex]

thanks a lot...

and also, i think if your wanting a more accurate estimate of uptime, if you get more monitoring on your servers from different locations(meaning websites) than it would be easier to see what your probably pulling off on uptime
