Quite close to the recent AWS outage. Let me take a look if its a major one similar to AWS. Any guess on what's causing it? In hindsight, I guess the foresight of some organizations to go multi-cloud was correct after all.

Trusting AI without sufficient review and oversight of changes to production.

Earlier quoted context omitted.

yea its not just the portal. microsoft.com is down too

Yeah, I am guessing it's just a placeholder till they get more info. I thought I saw somewhere that internally within Microsoft it's seen as a "Sev 1" with "all hands on deck" - Annoyingly I can't remember where I saw it, so if someone spots it before I do, please credit that person :D Edit: Typo!

I'll be interested in the incident writeup since DNS is mentioned. It will be interesting in a way if it is similar to what happened at AWS.

I bet it’s DNS.

“ Starting at approximately 16:00 UTC, we began experiencing DNS issues resulting in availability degradation of some services. Customers may experience issues accessing the Azure Portal. We have taken action that is expected to address the portal access issues here shortly. We are actively investigating the underlying issue and additional mitigation actions. More information will be provided within 60 minutes or sooner.

Looks like AWS is also impacted?

Yeah the graph for that one looks exactly the same shape. I wonder if they were depending on some azure component somehow, or maybe there were things hosted on both and the azure failure made enough things failover to AWS that AWS couldn't cope? If that was the case I'd expect to see something similar with GCP too though.

Edit: nope looks like there's actually a spike on GCP as well
