I run a site that monitors cloud service availability. Based on VMs and Blob storage containers I maintain and monitor, the outage affected every US Azure region with 1-2 hours of downtime: https://cloudharmony.com/status-for-azure

you need to add in the new Australian Clusters

You should try Google's App Engine (paid premium account) tech support when your critical files disappear. Can't be any worse than this ... That's the problem with these hosted cloud solutions, your systems are at the mercy of the bad tech support. Try explaining that to your own customers ...

Azure support is probably the worst one I had ever deal with. When my account (and service itself) stopped working, I haven't received any email. When I tried to sign in, all I got was some generic error saying "There's something wrong with your account". My services of course were down and I couldn't do ANYTHING. I've contacted the support to learn that my account has been blocked (!) because there was some suspicio…

Days? What do you "days"???? Azure was down for like 9 hours.

I think that he is not referring to this incident.

Wouldn't that kill DNS if everyone did that considering it relies on caching for performance across the world?

I'm no expert, but no. Most big sites rely on a fairly short TTL. It's a thick layer of caches. Your browser, OS, router, ISP, and a bunch of intermediaries can cache the DNS. So even at 60s, you get good cache hits (the busier, the more true that is, of course) Also, the update can always happen asynchronously. You and 9999 people ask your ISP for Facebook's IP. It serves all of you a slightly stale IP and asynchron…

But there is a difference between a big site and many small sites regarding DNS caching. If 10 big sites has 1 million requests each within an hour most requests will be cached. If 1 million small sites has 10 requests each within an hour most request will NOT be cached but forcing a cache-refill. I think that might strain the DNS infrastructure.

We've been noticing ups and downs for the last few hours of our VM powering an important database in West Europe.

Seriously considering another layer above azure to mitigate this in the future. Very disappointing to see.

At least initially their status indicated they're handing the problem but lately it's just been "All Good" and they said they resolved it on twitter but it's not at 100% yet: http://azure.microsoft.com/en-us/status/

I've never ever received a message from AWS when they've had outages that have been affected us significantly. On the contrary, there's been multiple cases where we've experienced issues, contacted them and it's taken a few hours before they realize they're actually having infrastructure problems. Many of these don't even get an entry on their service status pages. So there's still a lot of room for improvement on AW…

I can confirm this. I remember once when half of the Internet was down and the status reported for EC2 was yellow - experiencing some minor issues :-) And I find out about it by yelling at Heroku - they told me that Amazon is having issues before Amazon's status turned yellow.

Usually when AWS has an outage they have a nice green circle but with a small blue "i" next to it that you need a loupe to see. Extremely dishonest.

They all have outages periodically, in my experience.

Yeah, that's the main thing to take away from these events. I've never seen a system (cloud, local, co-located, or otherwise) with 100% uptime, despite every effort to the contrary. Even sites like Facebook and Google have downtime. In the last few years that I've been using it, Azure has been at least as stable as other cloud providers. That doesn't help with the awful timing though. Ouch. I just Buffer-retweeted yo…

For nine hours?
