Judging by how cloud services "frequently" go down when everything is normal, it makes me wonder what would happen in case of a real problem (volcano eruption, social unrest, nuclear disaster, alien invasion ...). I still don't get the cloud infatuation, and no you don't have to get off my lawn, I'm "only" 36 (yeah I know, in IT I'm already a dinosaur).

What would happen to your own datacenter in case of a similar disaster? Your servers would go down and you would spin up from your disaster recovery site. Cloud doesn't mean you don't need a DR plan anymore. Put your servers in different regions, use Azure/Google, BlueMix/AWS, or even hybrid cloud, do something. Have a DR plan.

I'm thinking as the little guy here : not data center but personal computers.

If the disaster strikes my region, I probably have better things to do than IT things (like running for my life :-).

But with the cloud the disaster could be thousand of kilometers away and still affect me. That's the problem with the cloud : why should I stop working in my remote French town because there's a landslide in Ireland (or wherever they put the European cloud data centers) ?

I don't say the cloud doesn't have it's uses (especially as a redundant backup far far away) but the all cloud model has way more risks than what people think ... and vendors don't rush to explain that.

I'm one of those guy that think the future will be more and more harsh for the western civilization (think collapse of the Soviet Union). There will be less money for everything, infrastructure in particular, things will fail and you will have to deal with it locally and the DIY way.

This may be greater then just west Europe. I personally have servers in US East that are unreachable, and there are a few reports of others in US region reporting partial unavailability for the US based servers. I wonder how many customers Azure just lost do to their unexpected 2 day fiasco

After hours of no response on the microsoft forums, VM's just started working again. I didnt change a thing, just poof.

2. Azure does not guarantee that you keep your ip address by default. You should configure a cname if you use Azure Websites or get a reserved ip address, available with Cloud Services

Actually, I am supposed to have a fixed IP. And I have CNAMES configured. I will review to determine if there is some other way I can set this up, but my issue is that I would never allow my products to be offline for hours without notifying my customers.

First, I am really sorry about the impact the incident had on your service. Specifically, for your changing IP, are you currently using the reserved IP feature. You can reserve both your external IP and your internal IP.

Azure has had quite a few outages this year. I'd say it's already lower than that 99.999 percent uptime or w/e they are advertising.

0.001% of 365 days is 8.76 hours. So yeah, shot for the year; but of course they'll do some "hollywood timekeeping" (or just ignore the matter altogether) and keep advertising...

0.001% of 365 days = 5.26 minutes (http://www.wolframalpha.com/input/?i=0.001%25+of+365+days)

Just apply same buggy network patch to all DCs at once? They use software networking so causing something like this should be easy. Or mess up network routing for *.blob.core.windows.net which pretty much all of Azure relies on.

Isn't applying the same patch everywhere at once a major anti-pattern?

Turns out this was exactly what happened - they applied a buggy patch to all data centers at once by mistake.

We used to have a locked "oh shit" box. I was supposed to put our DR (which we did actually have) and a host of other things in it (it was suggested we even put a loaded gun in it) to get by with in the case of a total disaster. We were supposed to then ship it off to Iron Mountain. That oh shit box sat empty for years on the premises...

You must have really interesting stories to tell, but I guess it's classified.
