We work with 3 providers. Today 2 of then go down. Just Linode is ok now.

ironically, we moved away from linode last month because they kept doing maintenance and turning off our machines without telling us

Linode sends out notices for every single maintenance event, which includes both emergency and scheduled events. The maintenance you experienced last month is explained here: http://blog.linode.com/2012/06/13/xen-security-advisories-an...

We learnt our lesson the hard way after the great AWScalypse of Apr 2011. The lesson: Use n>1 hosting companies (even if one of them promises a-z-multiregion-distributed-fault-tolerant-back-up)

My co-location provider's data center has had about four hours of downtime in ten years. It turns out a backup diesel generator, redundant connectivity, and a good network/sysadmin are all anyone needs.

People are now working out how to failover from AWS to Rackspace and that is infuriating to me. You... you need redundant clouds now? That can't be right!

My problem with them is they don't provide RFOs (Request for outage) because they can't give away any of the "propitiatory secretes" about their setup. I'd like to know what happened when it effects me. Also when it comes to replacing hardware or preforming maintenance, their priorities wont always line up with mine.

Does anyone else find it strange that two Heroku posts made the frontpage considerably (in relative terms, obviously) earlier than "EC2 down"? I would think EC2 is a more common denominator for people, but maybe other hosts have better redundancy and thus there wasn't an immediate awareness? Or am I just overly curious and it's really just that some Heroku clients happened to notice before an at-large EC2 customer? e…

a PaaS like Heroku ends up being "front line support" for AWS. if you use Heroku and your apps fail, you don't care if it is Amazon's fault - you blame Heroku

Am I at fault in believing this happens drastically less in Europe datacenters, for any cloud service?

I believe that, at least for AWS, the us-east data center is drastically larger than eu-west.

Larger, older, slower, more fragile. And cheaper.

Still down here, over 12 hours at this point. This is probably the second time we've been hit with something on AWS in the last three months -- and you have to pay them to talk to someone about it. We're definitely moving to Linode ASAP..

If your application needs to be up constantly, then it should probably be at least multi-AZ scaled, if not multi-Region. Multi-AZ applications are not affected by this outage, and multi-AZ events are very rare. Living out of a single AZ is very risky.

You're comparing different things: most of the complaints about AWS have been due to servers (EC2) or network storage (EBS) failing. The outage in March was networking related so that would count, however.

Everyone's A zone is different. So I could say A is down while someone else is saying B, and we could be talking about the exact same zone. It makes it difficult to say if it is more widespread or not.

Maybe I'm assuming wrong but I guess in your example zone A and B are the same and that the different zone names users see don't represent different ways of spreading resources. If so, why aren't they named consistently? If not, are there any details on how and why they've set up their zones (or am I overlooking another assumption I've made?)

Adding to the "why it's scrambled" comments: because data transfer pricing differs for intra- vs. inter- AZ traffic, if you need to coordinate with other entities to be in the same AZ, it's possible to do so.

But, yes, generally: Amazon randomly allocates AZ labels to given customers to avoid preferential clustering on any given first choice.
