Re: Linode, CloudSigma, and SoftLayer
Right, I'm totally with you on 99% seeming good but not good enough. I just think year to year numbers may not be good enough. You could have an outage on Jan. 1st of one year, and go all the way to December 31 of the following year to your next one. That one day shy of two years without an outage but both year's numbers would look bad. We need some sort of longer look and also some sort of median time between outages as well. And also, which is worse-- 1 one hour outage or 60 one minute outages?

Re: Linode, CloudSigma, and SoftLayer
@Dave, reliability is one of those areas where precision matters a lot. 99% reliability means that you can have over 3.5 days of downtime in a year. That's a bunch. In general, the money (in terms of both cost to maintain and cost to contract for services) really starts building when you move between four and five nines. A whole day can make an enormous difference when it comes to the number of nines to the right of the decimal place.

Your question about variability is a good one: I'd love to know that myself!

Re: Linode, CloudSigma, and SoftLayer
@Charlie- Obviously downtime is money and 40 hours versus 3 or 4 looks really big. It is ten times bigger, right? 

But I have just enough understanding of statistics to be dangerous. What is the variability of these numbers year to year? In other words, we know Amazon had a rough year two (three?) years ago when it had a multi-day outage. Can the same be said for any company? Jsut one bad day throwsyou from first to last in these rankings?

Because all of the companies here are at the 99% rate. A few hours seems to throw off the digits behind the decimal really fast.

Linode, CloudSigma, and SoftLayer
The small New Jersey provider, Linode, posted good numbes with 99.9953% uptime and a total 1.23 hours downtime for the year. CloudSigma had 99.964% availability, with 5.1 hours of downtime. Not clear to me why stats weren't offered on IBM SoftLayer compute.
