But Azure was broken yesterday! What changed?

It's not fun when you can't isolate a root cause for a problem

Some of the most frustrating issues in IT happen when a thing which was working fine stops, and you're sure you didn't change anything. Now that very few people host their own infrastructure, these issues can be compounded because change or problems might happen in the internals of a complex infrastructure system you have no control over. I got bitten by this recently, and while I have no answers I suspect this is worth writing up just because it may help other people to realise the problem you have is not always your fault...

Pay attention to the subtle details in your Devops pipeline YAML

Valid YAML doesn't necessarily mean working pipelines

Computers. Very useful when they work, but wildly frustrating when they don't. Recently I had one of those moments of frustration (well, two days actually) with Azure Devops and its YAML-based build pipelines. The root cause here seems like one of those things that could well bite others, so here's what happened to me...

I doubt this is a common problem, but still worth writing down in case it's a challenge for anyone else...

Broken Unicorn synchronisation

Ever had a tool that works reliably suddenly not work? I had a problem like that recently, and it lead to some experimentation that I think I may need to come back to later. So this is mostly so I can remember what I was doing when I get back to this. But as we move toward a more "platform agnostic" with more use of .Net Core on Linux, maybe there's something here that might help you too...

Security fun with Azure Kubernetes Service

I've been working on a deployment of Sitecore using containers recently, and hit a scenario which isn't discussed much in the Microsoft documentation: How do you go about setting it all up if you can't use Active Directory accounts across your DevOps and Azure instances? Having done some digging, here's what I've learned so far:
