100% uptime - is that possible?

I'm sorry, but that's just 7 days.. Show me 100% uptime for 12 months straight on a server full of clients and then I will be impressed. ;)

easyhostmedia, as he already mentioned above, was referring to that 100% uptime can be achieved, depending on the time frame we are talking about, 100% can easily be achieved for a day, a week, a month and even a few months easily.

I'll go as far as saying that with a lot of skill and even more luck (mostly with hardware/network), you can keep the server running, without downtime, for a long long time. However, in practice, this never happens as it'd be in your own best interest to perform some maintenance on a server from time to time.

yes i am aware what hostleet says , but the way likeahost wrote his comment like 100% was never possible, so i was just showing him it was possible to a point. normally my production servers will stay 100% for 45 days before i update/reboot unless they need anything before that time.

the server that i had running 184 days only runs RMS for all i have all the security etc. as all my other servers as it does not have clients, it does not need a lot of features so it does not get updates as much or needs rebooting as much
 
That is exactly what I tried to explain myself. It was based on a technicality of how likeahost phrased the statement. I am pretty sure HostLeet is on the same page on this one. :)

Exactly.. And, I also agree 100% with what you said regarding maintenance. Servers can easily achive 100% uptime, depending on what the server is used for. However, when it comes to servers used for hosting clients, you NEED to have downtime sometimes in order to perform upgrades/patches/updates/ect.. and keep your servers secure and optimized for the best performance possible. :thumbup:

I really doubt that there's anything such as 100% uptime. Not only are there routine maintenance that has to be done every so often, but THINGS HAPPEN. Very bad weather for example. I never thought 95% uptime was a bad thing though, because 5% doesn't seem like that big a deal. It probably matters more to business website since you guys lose customers that way.
 
99.9% is realistic hosting industry value. 100% is impossible. Even cloud solutions are experiencing some downtime.
 
Look for a minimum uptime of 99%. In fact, even 99% is actually too low - it really should be 99.5% or higher. The host should provide some sort of refund (eg prorated refund or discount) if it falls below that figure.
 
100% mean's no downtime ever!..... when you gonna reboot for kernel upgrades?

what about your data centre, network congestion/router failiure?


hard drive failiure?

someone cut's the cable outside your data centre (downtime should be minutes, but it's still downtime taking that 100% down to 99.9999%)

power failiure shouldn't happen (but it did here in the uk in one of bluesquare's facilities this year taking down lots of large sites)

there are million's of things that can happen to take that 100% downtime down and that's not taking into consideration the customer that thinks they can use all cpu power available and kill the server (requiring a restart to regain control)


so i agree that 100% uptime should be obtainable for short periods (and i'd be concerened if it weren't) over the course of a year it's impossible.

In a VMware environment it's easy to take a server out of the production environment to perform hardware/software upgrades. Virtual machines running on the platform are simply vMotioned to another physical host without missing a beat. The licensing is expensive with VMware but it does make a significant difference to uptime.

You can do the same with OpenVZ - live migrate a running container from one node to another without stopping / rebooting it.
It works > 95% of the times (sometimes it can't be done - i.e. if ntpd or other process using POSIX timers is running inside the container - in such cases a reboot of the container is needed).
 
computers are have their limits too, they would break down if they were to be used, 24/7/365* so 100% up-time is not possible, the closest virtually possible would be 95-97%

what a load of rubbish my computer is 5 years only and is on 24/7/365 and have never faultered.

you can achieve 100% uptime over short period of times
 
It is simply not possible. There is always a risc of your servers not acting the way you like or maybe even a hacker attack. You will just end up in a bunch of complaints from your customers if you choose to offer this service. Also most people with a brain would stay away from this
 
100% uptime guarantee doesn't mean that someone will sue you if you have below 100% uptime guarantee. You have to just pay SLA amount to customers, if case of any emergency events.

well if your servers cannot obtain 100% uptime over a short period (1 day, 1 week, 1 month) then i suggest you find another supplier.

100% uptime is possible over a short period.
