Tell HN: Azure outage

Posted by tartieret 10/29/2025

Azure is down for us, we can't even access the azure portal. Are other experiencing this? Our services are located in Canada/Central and US-East 2

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

It's possibly more likely that people mis-attribute the cause of an outage to the wrong providers when they use downdetector.

zavec 10/29/2025||

Definitely also a strong possibility. I wish I had paid more attention during the AWS one earlier to see what other things looked like on there at the time.

they recently had an incident with front door reachability, wonder if it's back.

This cannot be a coincidence

looks like MS completed a failover and things are be recovering slowly

Compare the comments and news coverage on this compared to the AWS outage... pretty telling.

Shut the front door!

We're quickly learning who's relying on a single cloud provider.

Multi cloud is really hard to get right at scale, and honestly not worth the effort for the majority of companies and use-case.

Like AWS or GCP? https://downdetector.com/status/aws-amazon-web-services/ - https://downdetector.com/status/google-cloud/

When you look at the scale of the reports, you find they are much lower than Azure's. seeing a bunch of 24-hour sparkline type graphs next to each other can make it look like they are equally impacted, but AWS has 500 reports and Azure has 20,000. The scale is hidden by the choice of graph.

In other words, people reporting outages at AWS are probably having trouble with microsoft-run DNS services or caching proxies. It's not that the issues aren't there, it's that the internet is full of intermingled complexity. Just that amount of organic false-positives can make it look like an unrelated major service is impacted.

Yup, see it as well.

AWS, now Azure - wasn't this a plot point in Terminator where SkyNet was causing computer systems to have issues much before it finally become self-aware?

Funnily enough, AI has been training on its own data as generated by users writing AI conversations back to the internet - there's a feedback loop at play.
