This is really annoying... Down 2 times in 3 days!
Have they broken your SLA?
They were down for us nearly 6 hours Saturday night, 1 hour this morning. They broke their SLA by a mile. Moving to EC2 asap.
Linode is down again

With 99.99% uptime: .0001 * 30 * 24 * 60 = 4.32 minutes With 99.9% uptime: .001 * 30 * 24 * 60 = 43.2 minutes
I think he just typo'd the %. From the terms[1]: Linode.com provides a 99.9% uptime guarantee on all Linode hardware, and on network connectivity. In any given month, if your Linode is down for more than 0.1%, you may request a pro-rated credit for the down-time. [1]: http://www.linode.com/tos.cfm
Wait so the only backlash they get should they break their guarantee is that they credit me for the down time? This doesn't seem like a motivating factor to keep uptime. Is this standard practice in the industry? I know prgmr has refunded me the entire month when they broke their SLA.
All that said, I won't be getting rid of my Linode box in Fremont simply because it's one of the best vps's I've had performance wise. It just seems like an odd SLA.

#33My London node was down briefly two days ago .. same happened about a month ago - is this a reason to worry?
I had the same problem, found a gap in the logs Linode provides. Didn't get any information about it though.

More than one server across multiple datacenters is the only way. The use either a load balancer (which brings its own problems) or some kind of status aware DNS scheme to route traffic to live servers. I wish linode would offer some kind of high availability load balancing like amazon ec2 does, that really is a killer feature.
I wouldn't be so sure that ELB's are actually failing whole IP addresses across availability zones. Given the current ELB architecture is heavily dependent on dynamic DNS resolution, I am pretty suspicious that they are using DNS for failover. The separate set of DNS servers specifically for elb.amazonaws.com and the 60 second TTLs on the CNAMEs they generate seem to indicate this. Of course, there is no documentatio…
Hmmm. Interesting point. However, if that were the case, why would ELBs be restricted to single AWS regions?
Anyway, its a nice feature that it just works without me needing to set it up.

use a DNS roundrobin with low TTLs and use monitoring to remove IPs when they go down. if you have 3 hosts in your production app's roundrobin, that makes it much less likely that they'll hit the dead server and if the TTL is 300, then it's only a few minute window anyway.
That's material for a great blog post. Please write an article wherever you can and share!
Visual Website Optimizer setup is exactly like this. We documented it here http://visualwebsiteoptimizer.com/split-testing-blog/maximum...
Re: Linode is down again
#36And to think how much time I spent last month recommending these guys, especially the Facebook-friendly Fremont data center. Awkkkk-ward.
Why? Because there are other services with no downtime?
Even Amazon and Rackspace go down...
Even Google has had outages...

It's a term of service (TOS) agrrement, not a professional SLA.
Most of us don't pay Linode anything important enough to warrant an SLA.
You don't get very strict 99.9% SLAs for $20 and $80 a month anyways...

Linode has a 99.99% uptime guarantee, which amounts to 43 minutes and 12 seconds offline in a 30 day month. While I don't have a Linode in Freemont, their status page appears to indicate, at minimum, 1 hour of downtime. As repayment for the inconvenience, users get the lost time added to their balance.
A 99.99% uptime guarantee would be 4.32 minutes per month. You calculated for a 99.9% uptime guarantee.
I'm going to take a long break from ever doing math again on HN.

What is EC2's SLA, and what cases of downtime have they experienced over the past couple of years? I'm assuming you wouldn't change providers without first finding this out?
