Unlike Microsoft, Google can claim 99.9 percent cloud uptime

By | September 28, 2011, 5:38am PDT

Summary: Google can legitimately say that its service has 99.9 percent uptime, unlike Microsoft, which is still being investigated over false advertising claims.

For those who thought that no company in the cloud space could legitimately offer “99.9 percent uptime”, it turns out Google can.

Last year, Gmail for consumers and Google Apps customers achieved 99.984 percent uptime, and was up for 99.99 percent for the first quarter of this year — equating to less than five minutes of downtime on average per month.

As part of Google’s service level agreement, just as Microsoft does, the company will offer customers a certain amount of free days of service in each billing cycle if it cannot meet the level of availability it says it can.

But Google admits that it “isn’t perfect”. In trying to be so, the search giant has developed a new Apps Status Dashboard to provide faster, more accurate and up-to-the-minute information on outages in a timeline format.

According to Gartner research, cloud-hosted services account for between 3-4 percent of the overall enterprise email market. Google only has a fraction compared to Microsoft or other providers, but takes up nearly half in the total cloud email market.

One thing is clear, is that though Microsoft may have the greater numbers on its cloud-based email services, it cannot boast the greater reliability or uptime — the crucial factor in any outsourcing decision.

UK authorities are currently investigating Microsoft’s claims that its 99.9 percent cloud uptime is in fact true, after a series of outages left Office 365 users without email or communications.

The Advertising Standards Agency is investigating a complaint over “marketing communication on Microsoft’s website” specifically in regards to the uptime claims the company makes in its advertising material.

Microsoft’s next-generation cloud email service, Office 365, which launched earlier this year, replaces the trouble-ridden Business Productivity Online Services (BPOS), which was famed for its downtime.

False advertising? Is that what they call crappy luck/growing pains nowadays?

Zack Whittaker's blog post seems to be suggesting that Microsoft would be better off doing what Google does. And Google's strategy is to publish their own very special definition of "uptime" and then focus on that -- thus not having to worry so much about the other very real issues that can and do affect users of Google could services.

Google's strategists knew exactly what they were doing when they carefully crafted their definition of "up time" in their small-print -- that's why Google has 99.9% uptime, and more importantly that's why they wasted no time in drawing so much attention to this issue, and why Microsoft's figures were suddenly scrutinised so thoroughly (a challenge which is ongoing, so let's not draw any conclusions just yet).

During Google's glorious period of so called 99.9% uptime, I lost all my emails, contacts and data from my Gmail account -- if that's what Google calls 99.9% uptime, forgive me if I don't join in the traditional chorus of hymns singing the praises of Google based on the gospel of the unquestionable corporation's own propaganda.

@Tim Acheson So YOU lost all your information (did any of it come back? How long did it take? When did this happen?)
Without complete answers, it appears merely anecdotal, and at 1 person out of how many thousands/millions, still makes it WAY less than 0.1% downtime.
@Tim Acheson Hi Tim, I work for Microsoft O365 and wondered if you have tested out our new cloud service for email and productivity? Thanks@

Google uses this OS

http://kernel.org/

The one that has been down for maintenance for a month. That is 0% uptime BTW.
@toddybottom
The OS is not down for a month. As far as I am aware all my Linux computers (laptops, desktops, servers) both at home and at work are up and running.
@toddybottom: I assume you're aware that very few expect it to have been hacked using an exploit in Linux itself.
thehackernews.com/2011/09/kernelorg-server-rooted-and-448-users.html
It is pretty much always user error. In a few cases, the systems were not updated on time when security patches had been released.
Still much more rare than the exploits all these botnets usually use on That Other OS.

Linux uptime wins every time.

PS. There is no need to reboot Linux.

Really? I'm told to reboot my Linux box at least once a week thanks to updates.

" I'm told to reboot my Linux box ..."

You are told wrong. Period.

PS. Formal training may help.
@Cylon Centurion

Some distros take the easy way out and make you reboot for every update that requires a service restart. A good distro knows how to quickly restart a service without a reboot.

However the same can be said of Windows with many third party apps. The difference is that if you rely on a third party Windows app that does that you are at their whim, whereas you can always get a better distro if you use Linux.
@Cylon Centurion
kernel updates every week? Wow, you are full of poo.

Since my last post was deleted, let me rephrase:
If you claim that you have a kernel update every week you must be lying.

@Cylon Centurion
If you want to run the latest version of the Kernel. It does not take years to release a new version of the OS.
You must also have seen that the old habit of Windows was never present. Install something, reboot? Change a setting, reboot? Have a problem, first try to reboot?
For 10+ years I always saw Windows as some game machine with extra features. Problems, cut the power. They made progress but for me they still do not look really professional, what ever the marketing says.
@Cylon Centurion: Unfortunately Ksplice and the other metohds (AFAIK there's at least one other) haven't found itself into Ubuntu and other end-user distros yet. I hope they will soon.

@the_flagger

Did the OP really deserve a flag?

PS. It could've been done for only and only one reason.
To suppress the truth? It could have value to someone.
One outage is enough to spoil the entire year's statistics. Google just got lucky...

Get real... there is nothing like 100% cloud uptime. 99.99 or 99.98 what difference does it actually make? Even Local or onsite services can't guarantee 100 percent uptime.

Regarding UK authorities investigation, they should probably ban the broadband advertisements first. How many providers show the real picture in ads? 99.999 percent of TV ads are exaggerated.

Only idiots will believe that TV ads and fully accurate.

Thanks Zack, now for the facts
facebook@... 28th Sep
Unlike Microsoft, Google arbitrarily decides what is included in the SLA.

1. Downtime is defined as "significant". if 1% of the users are affected, there is no downtime.

2. Downtime is defined as anything over 10 continuous minutes. You could have hours of downtime in a day. as long as those hours are spread out over 9 minute increments.

3. Downtime is tied to only certain services: App engine down? too bad, doesn't count. Imap down? so what?

Seriously, try to dig a little deeper in your stories instead of regurgitating press releases.
Exactly. What's your Twitter handle? I want to follow you.
@Tim Acheson IF you are @timacheson on twitter, I recently followed you today. Just look for the dog avatar.
@Tim Acheson Not exactly. He's wrong. See the comment above.
@facebook@...

Well Said.
@facebook@... Your information is out of date. I can't find the link, but Google changed from 10 minutes to any amount of time several months ago, and by server error rate, not customers affected. From their SLA:

"Monthly Uptime Percentage" means total number of minutes in a calendar month minus the number of minutes of Downtime suffered in a calendar month, divided by the total number of minutes in a calendar month.

App Engine is moving from a mostly free service to a paid service, and is getting an SLA:
During the term of the applicable Google App Engine Agreement, Google will make commercially reasonable efforts to keep the Google App Engine service (the "Service") operational and available to Customer at least 99.95% of the time in a monthly billing cycle (the "Google App Engine SLA" or "SLA").

Seriously, try to dig a little deeper for your comments and keep your criticisms current.

By the way, why do you bother to read Google stories at all when your only comments boil down to "Google sucks." It seems like you need to visit _every_ story about Google and drop a ripe comment. Just stop reading and commenting, and let the rest of us have a real discussion.

Has anyone actually found the 99.9% uptime claim?
toddybottom Updated - 28th Sep
Where did MS actually claim to have achieved 99.9% uptime? I've seen quote after quote where MS states that they have a financially backed 99.9% guarantee but that is not the same thing as claiming to have achieved 99.9% uptime.

I asked this the last time this article was posted and got no answer, presumably because this claim does not exist. So I'll ask again, where did MS claim to have actually achieved 99.9% uptime?

Disclaimer: I use Google Apps a lot and really like it. I do not use any of MS's cloud services.

This article provides little value. One can slant a statistic a million & one ways. This is a great example of that. If you look at the fine print in Microsoft 365's Service Level Agreement (SLA) vs Google Apps for Business' SLA you will see that they define uptime/downtime differently... always to their advantage.

For example, Google Apps for Business SLA does not count an outage as an outage if: 1) less then 5% of their domains users are effected, 2) a service such as Postini Archiving or Google Voice is down for 100% of your domains users, etc, 3) when a natural event such as a lighting bolt takes out their data center. This actually knocked out MS and Amazon's Dublin, Ireland data center earlier this year since their infrastructure wasn't redundant enough, etc. and left many of its subscribers in the dark. If this happened to Google the outage would not be included in "downtime".

Moral of the story. Read the vendor's SLA to know what 99.9% actually means so that your company is not at risk of a big surprise.

Expensive
somereader Updated - 28th Sep
I must be expensive to run such a thing on non Linux servers. Linux is very flexible, can be adapted for many purposes. Look at the speed of search in Google. How they can use farms of computers to distribute the load.
I suppose MS can, for PR reasons not use Linux. It must be their own stuff. But I do not think that all they need is already in their catalog. So, that creates work. And a higher risk for errors.
@somereader It's not that expensive if you can just add Windows licenses and CALs as you see fit without having to purchase them first, as in Microsoft's case. For the rest of us running a flexible data center on Windows ....
It is interesting that ZDNET decides to delete every post of mine here. Even if it is completely within the scope and complies with all the rules of the forum.
In any case here is briefly what I had to say:
A. Linux does not need weekly reboots as facebook says.
B. MS SLA also does not count as outage "...when a natural event such as a lighting bolt takes out their data center.."
C. They do not even count "scheduled service" as an otage. Obviously MS has not heard of building redundancies.
D. MS SLA clearly states they count downtime as the time service is down multiplied by the percentage of affected users. So if 10% of users are affected for 7hrs per month this is 99.9% uptime.
I don't see where Microsoft claims to have 99.9% uptime. They only claim to offer financial rewards if they do not meet 99.9% uptime. Those are two different things entirely. So basically, they strive to meet 99.9% but customers make out financially if they do not.
@TimianLo That's the same claim that Google makes. The SLAs for both companies are for three nines.

Key point... how is uptime being defined?
Ugh... this is a waste of time 28th Sep
There is no standard being used across Cloud services. If all of you dick measuring pricks can check your ego's at the door
long enough to think about what is actually being stated, you may see past the hype and realize these folks "reporting" have to make money by getting you all worked up about something. (And the skill needed is called critical thinking jedi, no formal training required)

Finding track records of downtime isn't hard to do... locking down what all the different players are willing to commit to as being defined as downtime is the easy part for folks to ignore doing.

http://www.pcworld.com/businesscenter/article/172614/google_outages_damage_cloud_credibility.html
What is the uptime of Microsoft Cloud Services? Aside from the outage they had a while back I find that the service is always up based on the students and staff that use it in my organization as well as several other schools that use it constantly. So if Microsoft is 99.5% (as an example) uptime compared to 99.9% you are complaining about maybe an extra few seconds per month on average? Really?
