It seems they copied AWS S3 too well , including its "feature" of going down every now and then and it's overall lack of reliability. Nice!
That's true commitment.
DreamObjects is down

Re: DreamObjects is down
#12The name of the service is DreamObjects. No affiliation to Dreamhost but doing something as basic as storing files as a service hardly deserves to be called a clone.
It's not just storing files as a service in some generic way. It's storing objects using exactly S3's API (or at least a subset) so e.g. programs and libraries written to use S3 can use DreamObjects instead by just changing the base URL. That's a clone of S3 as much as Linux was a clone of UNIX, and as much of a clone as there can be when the original is closed source.
Disclaimer: I'm on the GlusterFS team at Red Hat, which puts me pretty close to the Ceph team but not actually one of them. I've never had anything to do with Dreamhost.

I've never seen S3 go down, the availability is 5 9's. EC2 has had outages in the past.
S3 went down in 2008 for a few hours. Lots of coverage at the time. e.g. http://techcrunch.com/2008/02/15/amazon-web-services-goes-do...

I've only had very minimal issues with S3... one of the things thats holding me back from switching to a cheaper provider from Amazon is if its not broke, don't fix it.

#15Status update says they're running Ceph, an S3 work-alike. I don't want to say "clone" because nobody outside Amazon really knows how S3 works, and Ceph merely has an external HTTP API that supposedly works the same way. Is anybody running Ceph at scale and might be able to comment on what broke down?
I'm interested in Ceph-in-production stories as well. I subscribe to this feed http://www.sebastien-han.fr/blog/ which follows Ceph development and have been toying with the idea of testing it when time permits. Currently we use local storage for VM hosts provided by LVM but something distributed and designed with HA in mind would be helpful.

A couple hours for one location in 6 years is hardly the routine occurrence which the original commenter was claiming

All of AWS has changed significantly in the past 6 years. I think it's disingenuous to say that an outage from that era, for any provider, influences your thinking nowadays.

I wasn't saying it was, merely reporting the facts! S3 targets four nines uptime; which is really good but not infallible. For most apps though, I think it's reasonable to accept that if S3 is offline, the app is offline also.

I'm not sure S3 has changed nearly as much as the rest of AWS, which is probably why it is so stable. Regardless, the point is that outages can happen to S3 as well, and have; just because it hasn't happened for a few years doesn't mean than 99.99% = 100%.

In fairness high availability is usually measure per annum, on that metric S3 is 100% for the last 5 years.
Also a few years doesn't really imply 6 years to me.
