> The issue is causing impact in waves, peaking approximately every 30 minutes. Does anyone have any general ideas on what kind of outage manifests itself like this? Devices retrying to authenticate every 30 minutes and finding the service is down perhaps?

The point is PR. Never trust a status page if it's not directly connected to the monitoring system.
They never attach it to the monitoring because monitoring systems usually generate a lot of false positives which affect their published SLA.
And so updates to the status page become political and locked behind senior management approvals.. like AWS.

Were you using Standard HDD disks? They have a really poor SLA, and are only usable for things like stateless VM Scale Sets or otherwise redundant services. We had to switch everything to SSD to get reliability comparable to on-prem VMware.
No entirely SSD. The problems stopped after a couple of weeks suddenly.
This was circa 2018 but AWS was so much more stable at that time. Ok, US-E-1 AWS had issues from time to time but they acked them and fixed them
Does the Internet Archive use Azure? archive.org is throwing 503s
This makes you wonder if some centralization patterns, i.e. Azure AD, are not a national security problem?
Azure AD is a nightmare. I don't know how many of you sign in to multiple tenants in the console, but it generally involves buying a new computer.

For a development team, here's an example of something good about Azure: Microsoft gives us dev accounts with monthly Azure credits (e.g. $100) and you cannot spend more when those credits run out because there is no credit card etc. behind that account to charge the excess. Azure just like other cloud services (I've used AWS but as I understand it GCP is the same) doesn't believe in timely billing. You can and will…
> For a development team, here's an example of something good about Azure: Microsoft gives us dev accounts with monthly Azure credits (e.g. $100) First analogy I thought of were stories about drug dealers giving away free samples to schoolchildren to hook them up before asking for money.
Nobody is under any illusion that Microsoft just really likes universities for some reason. But on the other hand, we did need lots of this stuff and it's very cheap, budgets are tight and it's not as though hand-rolling even more stuff would be cheaper - we do hand roll some things where it makes sense.
For example, periodically senior people say "Why do we spend $$$$ on a supercomputer? Surely we could rent one from the cloud?" and we (well, not me, different group same department) go OK, we will cost that for you. And they get Azure, Google, etc. to quote them for what they need a supercomputer to do, and then they present this, "The Cloud providers can do that for $$$$$". Ah, that's more money. No thanks, we will continue to run our own supercomputer.
It's not even close. Cloud supercomputer is great if you need the supercomputer for six weeks to do a special project and then you're done with it, the Cloud provider saves you a lot of money. But the University needs supercomputers all the time, so the numbers do not work.

Azure Active Directory is not Active Directory but on Azure.
the people buying these things obviously have no idea about that. Migrating to Okta or something else neutral would cost the same, but hey, that's a different name

Works equally well. See the point?
