Azure is experiencing DNS issues in all regions

181 pointsby HEHENEabout 6 years ago
http:&#x2F;&#x2F;azure.microsoft.com&#x2F;en-us&#x2F;status&#x2F;<p>Looks to be a global outage across Americas, Europe, APAC, and Africa. Office 365 is still up for us, but colleagues are saying theirs is down as well.

Gitlab is also currently reporting issues with GCE. I&#x27;m unable to push to their network right now.<p>Looks like all three major cloud platforms are experiencing problems right now. Could be internet related?<p><a href="https:&#x2F;&#x2F;downdetector.com&#x2F;status&#x2F;windows-azure" rel="nofollow">https:&#x2F;&#x2F;downdetector.com&#x2F;status&#x2F;windows-azure</a><p><a href="https:&#x2F;&#x2F;downdetector.com&#x2F;status&#x2F;google-cloud" rel="nofollow">https:&#x2F;&#x2F;downdetector.com&#x2F;status&#x2F;google-cloud</a><p><a href="https:&#x2F;&#x2F;downdetector.com&#x2F;status&#x2F;aws-amazon-web-services" rel="nofollow">https:&#x2F;&#x2F;downdetector.com&#x2F;status&#x2F;aws-amazon-web-services</a>

Man... Azure seems to be an order of magnitude worse than AWS and GCP when it comes to reliability.<p>Seems like they have tons of global dependencies within their services which cause these cascading failures rather often... Seems like only a few months ago we were reading about a global outage that affected auth?

Azure has been magnitudes more expensive and magnitudes more unreliable for the one of our clients that demands we use it to host their stuff than either AWS, Digital Ocean, or Heroku.<p>Honestly, I can&#x27;t think of a single reason why I would recommend them over anyone else at this point, no matter what your hosting or storage or computing needs were. Can&#x27;t see a single area where they are better than the competition.

I’m at a complete loss how in 2010’s they can design build and implement a cloud provider, from the ground up that has so many “global outages”<p>This isn’t “legacy” code that has migrated from cobol to vb to c#, this is modern code and to suffer this bs time and time again is unforgivable

This is not new. DNS queries didn&#x27;t respond to Outlook (Hotmail) servers from within Azure. Thus the application I was responsible was unable to send emails via SMTP. And this issue appeared few times in the last few years.<p>Our customer was bashing us if they were unable to use our product for several minutes but when Azure was down for a day there were no complaints to Microsoft. (they were hosting our product at Azure)<p>I don&#x27;t understand their love of Microsoft. I guess because they have Microsoft certificates like generals have.

I wonder if this DNS outage will cause data lose like the last one....<p>The entire &quot;heres free ELA credits for Azure, please please Mr Sr Director&#x2F;CIO use Azure&quot; seems to be working, but then they go and do stuff like this.

Yep, we&#x27;ve just had one of our environments alert us. Services totally unresponsive - even the Azure portal was unresponsive. Affecting services we run in the US and Europe.

Ok, many of these cloud platforms charge <i>more</i> if you have things duplicated across regions&#x2F;zones. EG. AWS has multiAZ. Why pay for this? When AWS has a major issue - all zones&#x2F;regions are fucked in some way.

This would explain why my app kept throwing this exception when attempting to call an Azure SQL instance:<p><pre><code> System.ComponentModel.Win32Exception: No such host is known</code></pre>

Looks like the core problem today was a DNS zone delegation issue during a migration off of legacy DNS servers. I&#x27;m not sure how this type of issue can easily be segmented by region due to the way the DNS service is designed and fundamentally zone replication works.<p><a href="https:&#x2F;&#x2F;azure.microsoft.com&#x2F;en-us&#x2F;status&#x2F;history&#x2F;" rel="nofollow">https:&#x2F;&#x2F;azure.microsoft.com&#x2F;en-us&#x2F;status&#x2F;history&#x2F;</a>

Forgive my ignorance, but how do things like this happen at such a massive scale? I would understand maybe one big area shutting down because of some sort if internet network issue, but then there should be some redundancies in place no? I don&#x27;t get how it just all goes down across the globe, is there one master-computer that has just gone down, taking everything with it?

One would think after that 2016 Dyn outage people would strongly consider having an alternate DNS provider....

Tons of people arguing one way or another here. Does anyone have actual statistiks on reliability og different cloud providers across different zones?

My company is working on a project to move a customer web portal to Azure. This scenario was brought up and dismissed even though when events like this happen many of our customers would certainly come to our web portal as part of assessing the impact. I don&#x27;t expect this to impact the project though. The decisions have already been made.

All the big clouds regularly have outages.

I wonder if this is why www.cdc.gov is (was? appears to be back) offline.
